What is 2x plus 32x plus 3?
That's pretty easy. Just add the like terms (2x and 32x) and keep the 3. You get 34x plus 3.
What is 2x plus 3 equals 9 what does x equal?
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
What is 3 2x - 3 x plus 1?
If you mean: 32x-3x+1 then it can be simplified to 29x-1
4x-3 equals 2x plus 5?
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
What is X 2x-1 equals -3?
2x-1=-32x=-3+1x=-2/2x=-1

What is 2x plus 3 equals 9 what does x equal?
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
Find the value of x if 13 plus 2x equals 3?
13 + 2x = 32x = 3 - 132x = -10x = -5
Evaluate 3 open parentheses10x plus y close parentheses plus 2x plus 7y?
3(10x + y) + 2x + 7y (multiply the 3 through the parentheses then combine like terms) = 30x + 3y + 2x + 7y = 32x + 10 y Evaluate an expression for some values of x and y, means to substitute those values into the expression, such that when x = 3 and y = 1 the value of the given expression is 106: 32x + 10y = 32(3) + 10(1) = 96 + 10 = 106
What is 3 2x - 3 x plus 1?
If you mean: 32x-3x+1 then it can be simplified to 29x-1
How do you solve x plus 3 plus 2x equals x plus 9?
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
4x-3 equals 2x plus 5?
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
2x-3y equals 3 5x-4y equals 4?
2x - 3y = 3 ------ Eq.1 multiply this by -55x - 4y = 4 ------ Eq.2 multiply rhis by 2_____________________________________ the result after multiply both equation-5 ( 2x - 3y = 3 )2 ( 5x - 4y = 4 )_________________-10x + 15y = -1510x - 8y = 8_________________ by using the elimination method the result will be7y = -7y = -7/7 ,,,,,,,,,,, Y = -1to find the value of X, put the value of Y in Eq.1 :2x - 3y = 32x - 3(-1) = 32x + 3 = 32x = zero ,,,,,,,,,,, X = Zero
What is X 2x-1 equals -3?
2x-1=-32x=-3+1x=-2/2x=-1
What is 3 times 3 power 2x times 3 power negative 2 minus 3 power 2x times 3 and why?
I read that as: (3) x (32x) x (3-2) - (32x) x (3) = 32x(3 x 3-2 - 3) = 32x (3-1 - 3) = 32x-1(1 - 32) = -8 x 32x-1 When multiplying the same base (number) to any power, keep the base and add the powers, eg: 32x x 3-1 = 32x + (-1) = 32x-1 3 x 3-2 = 31 x 3-2 = 31-2 = 3-1
Each of the numbers below is a solution of the inequality 2x plus 3 greater than 7 except?
2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.
What is X and y intercept of -2x plus 3?
if:y = -2x + 3then:if y = 0:0 = -2x + 32x = 3x = 3/2if x = 0:y = -2(0) + 3y = 3So the x-intercept is at {0, 3}, and the y-intercept is at {3/2, 0}
