What the answer to 7n-2 3n 4?
To find the answer to the expression 7n - 2 - 3n + 4, you first simplify by combining like terms. Combine the 7n and -3n terms to get 4n. Then, combine the -2 and +4 terms to get +2. Therefore, the final answer is 4n + 2.
How do you do this A x 3 a plus 12?
Simplifying a = 3a + 12 Reorder the terms: a = 12 + 3a Solving a = 12 + 3a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3a' to each side of the equation. a + -3a = 12 + 3a + -3a Combine like terms: a + -3a = -2a -2a = 12 + 3a + -3a Combine like terms: 3a + -3a = 0 -2a = 12 + 0 -2a = 12 Divide each side by '-2'. a = -6 Simplifying a = -6

How do you Simplify the expression n plus 2n plus 2?
Combine like terms to give 3n + 2
What are the steps of addition and subtraction of algebraic expressions?
Adding algebraic expressions is performed by adding the coefficients of like terms. For example, to add (1) 3x2 + 2x + 12 to (2) 5x2 - 3x + 6 you combine the "x2" terms as follows: (3 + 5) x2 = 8x2 then you combine the "x" terms: (2 - 3) x = - x then you combine the constant terms: (12 + 6) = 18 so the result of the addition is: 8x2 - x + 18 To subtract equation (2) above from equation (1), you negate all of the terms of equation (2) and then add them as in above, producing: -2x2 + 5x + 6 QED.
How do you solve 2- bracket y plus 2 bracket equals 3y?
2 - (y + 2) = 3y Remove brackets: 2 - y - 2 = 3y Combine like terms: 0 = 4y Divide both sides by 4: 0 = y

Simplify 2-8x-x plus 4?
2 - 8x - x + 4 Combine numeric terms: -8x - x + 6 Combine x terms: -9x + 6 or 6 - 9x If you want, pull out common terms: 3(-3x + 2) or -3(3x - 2)
Are a negative number and a positive like terms?
i think yes, because you can combine 2 and -2, which are like terms, so why not 2a and -2a?
The sum of two numbers is 19 and their product is 78 What is the larger number?
Let x and y be the two numbers. 1) x + y = 19 2) xy = 78 Solve (1) for y. Subtract x from both sides. y = 19 - x Then we can write equation (2) as x(19-x)=78 Simplifying x(19 + -1x) = 78 (19 * x + -1x * x) = 78 (19x + -1x2) = 78 Solving 19x + -1x2 = 78 Solving for variable 'x'. Reorder the terms: -78 + 19x + -1x2 = 78 + -78 Combine like terms: 78 + -78 = 0 -78 + 19x + -1x2 = 0 Factor a trinomial. (-13 + x)(6 + -1x) = 0 == Set the factor '(-13 + x)' equal to zero and attempt to solve: Simplifying -13 + x = 0 Solving -13 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + x = 0 + 13 Combine like terms: -13 + 13 = 0 0 + x = 0 + 13 x = 0 + 13 Combine like terms: 0 + 13 = 13 x = 13 Simplifying x = 13 == Set the factor '(6 + -1x)' equal to zero and attempt to solve: Simplifying 6 + -1x = 0 Solving 6 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1x = 0 + -6 -1x = 0 + -6 Combine like terms: 0 + -6 = -6 -1x = -6 Divide each side by '-1'. x = 6 Simplifying x = 6 == x = {13, 6} The answer to your question is that the larger number is 13.
How do you add 2 square roots together?
It depends on which square roots. I think some examples will help. I will write S(2) to mean the square root of 2 for this answer. So S(2)+S(2)=2S(2). There is no other way to combine them. However, S(8)+S(2)=S(4x2)+S(2)=2S(2)+S(2)=3S(2) So you can combine. Basically, you combine like terms and whenever possible try to create like terms. If you had S(21)+S(19), they are NOT like terms and there is nothing more you can combine. You are done.

What is (4x-5)and(2x+7) in simplest form?
Simplifying 4x + -5 = 2x + 7 Reorder the terms: -5 + 4x = 2x + 7 Solving -5 + 4x = 7 + 2x Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -5 + 4x + -2x = 7 + 2x + -2x Combine like terms: 4x + -2x = 2x -5 + 2x = 7 + 2x + -2x Combine like terms: 2x + -2x = 0 -5 + 2x = 7 + 0 -5 + 2x = 7 Add '5' to each side of the equation. -5 + 5 + 2x = 7 + 5 Combine like terms: -5 + 5 = 0 0 + 2x = 7 + 5 2x = 7 + 5 Combine like terms: 7 + 5 = 12 2x = 12 Divide each side by '2'. x = 6 (your answer)
How do you do this A x 3 a plus 12?
Simplifying a = 3a + 12 Reorder the terms: a = 12 + 3a Solving a = 12 + 3a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3a' to each side of the equation. a + -3a = 12 + 3a + -3a Combine like terms: a + -3a = -2a -2a = 12 + 3a + -3a Combine like terms: 3a + -3a = 0 -2a = 12 + 0 -2a = 12 Divide each side by '-2'. a = -6 Simplifying a = -6

How do you simplify 6a2 - 6ab plus 7a2?
To simplify the expression 6a^2 - 6ab + 7a^2, first combine like terms. Combine the terms with the same variable (a) raised to the same power. This results in 13a^2 - 6ab as the simplified expression. Remember to keep the terms in standard form with the variable term first, followed by any constant terms.
