Combine like terms 3x plus x?
3x + x = 4x
Definition of like terms?
Like terms in mathematical problems are two variables that are the same. An example is 3x, x, 76x; because they all share x, they are like terms.
How do you simplify 3x-7-4-x?
Collect like terms together: 3x - 7 - 4 - x = (3x - x) + (-7 - 4) = (3 - 1)x + (-11) = 2x - 11
-x2 plus 3x equals -4?
-2x + 3x = -4 By combining like terms we get: x = -4.
What are the rules for combining like terms?
When combining like terms like 2x+3x we add their coeffitients, for example 2x+3x=(2+3)x=5x
What are similar terms?
They are terms that have the same variables like x, 2x and 3x or x2, 2x2 and 3x2
-3 plus 3x plus 6x equals 15?
-3 + 3x + 6x = 15 combine like terms 6x and 3x are like terms as are -3 and 15 9x = 18 x = 2
What are similar algebraic terms?
They are terms that have the same variables like x, 2x and 3x or x2, 2x2 and 3x2
Multiply (x - 6)(3x2 plus 10x - 1)?
Multiply each term of the second expression by each of the terms in the first expression and add them together, collecting like terms together: (x - 6)(3x² + 10x - 1) = x(3x² + 10x - 1) + (-6)(3x² + 10x - 1) = (3x³ + 10x² - x) + (-18x² - 60x + 6) = 3x³ + 10x² - 18x² - x - 60x + 6 = 3x² + (10 - 18)x² + (-1 - 60)x + 6 = 3x² - 8x² - 61x + 6
What is -3x-7 plus x-9 simpifed?
The expression reads as this: -3x-7+x-9 Combine like terms. -3x+x-7-9 -2x-16 If you would like to factor the expression, you can take out the coefficient -2, giving you -2(x+8).
How do you solve 6y-3x-9(1-1)?
6y-3x-9(1-1)=6y-3x-9(0)=6y-3x-0=6y-3xOnly like terms can be simplified. A like term has the same variables, X and Y are different variables. 6y-3x cannot be simplified because they are not like terms.
