How do you solve 5x + 30= 3( x + 4)?

1 Answer

x=-9

Explanation:

5x+30=3x+12 (Take out the parentheses by multiply 3 by the numbers inside the parentheses)

Take 3x to the other side because you do not want 2 separate x's.

5x-3x+30=12

2x+30=12 (Simplify so that there is only 1 x.)

Take the 30 to the other side.

2x=-18

Now take 2 to the other side and divide it so now, x will equal -9.

x=-9
