Question

How to do: 4(x+7)=2(x+7)

Answer 1

4(x+7) becomes 4x+28 you multipli the 4 in parentheses ans 2(x+7) becomes 2x+14

4x+28=2x+14 you move the x termes to the left and other numbers to the right look:

4x-2x=14-28 when you change the sides always change the sign +or-
2x=-14
2x/2=-14/2
X=-7

Answer 2

In this question, you're solving for x.

Solve for x:

4(x+7) = 2(x+7)

use distributive property

4x + 28 = 2x + 14

subtract 2x from both sides

2x + 28 = 14

subtract 28 from both sides

2x = -14

divide both sides by 2

x = -7
