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

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
