<span>To answer this question, you need to know the rules to move a number to the left or right side of the equal sign. To solve this, you need to move all the x into one side, and then move the number into another side. The calculation would look like this:


2(x – 3) + 5x = 5(2x + 6)
2x -6 +5x = 10x +30
2x+ 5x - 10x = 30 +6
-3x= 36
x= 36/-3= -12</span>

I got -12

2(x-3)+5x=5(2x+6)
2x-6+5x=10x+30
7x-6=10x+30
-3x=36

Divide using long division. Check your answer.

Answer:

x = 4

Step-by-step explanation:

(5x2 - 2x + 1) = (x - 1)

Simplify by multiplying 5 and 2.

(10 - 2x + 1) = (x - 1)

Combine like terms. Remove parentheses.

11 - 2x = x - 1

Cancel out - 2x to get the variable on one side.

- 2x + 2x = 0    x + 2x = 3x

11 = 3x - 1

Do the same with the 1.

12 = 3x

Divide.

x = 4
