An equation is shown below:

4 (2x - 5) + 15 = 11

Write the steps you will use to solve the equation and explain each step.

1. Distribute the 4 with (2x-5)

2. Then add 15 to - 20

3. Isolate x by adding 5 to the other side of the equal sign

4. Finally divide by 8 on both sides

I'm assuming that your solving for x ...

4 (2x-5) + 15=11

First you want to distribute the 4 into the parenthesis.

4*2x 4*-5

8x - 20

8x-20+15=11

Next combine like terms.

-20+15

-5

8x-5=11

Next step would be getting the x alone so add five to both sides.

8x-5=11

+5 + 5

8x=16

Finally, furthering the previous step, you divide each side by 8.

8x=16

/8 / 8

x=2
