Question

Solve 2x – 5 = 3(2x + 5).

Answer 1

First expand teh brackets. Are you able to do that?

Answer 2

yes

Answer 3

So: 2x-5 = (3 * 2x) + (3*5)
2x-5= 6x + 15

Answer 4

Move the term with the lower x (2x is lower than 6x) to the other side by subtracting 2x on both sides.

Answer 5

-5=6x - 2x +15
Simplify:
-5=4x +15
-20=4x
x=-5
