Question

Solve for x: 3x+2(x-1)=9x+4

Answer 1

Answer:

x = -3/2

Step-by-step explanation:

1) Expand.

$3x+2x-2=9x+4$

2) Simplify 3x+2x-2 to 5x-2.

$5x-2=9x+4$

3) Subtract 5x from both sides.

$-2=9x+4-5x$

4) Simplify $9x+4-5x$ to $4x+4$.

$-2=4x+4$

5) Subtract 4 from both sides.

$-2-4=4x$

6) Simplify - 2 - 4 to -6.

$-6=4x$

7) Divide both sides by 4.

-6/4 = x

8) Simplify 6/4 to 3/2.

-3/2 = x

9) Switch sides.

x = -3/2
