An equation is shown below:

4(2x - 5) + 15 = 11

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

4(2x -5) + 15 =11

Subtract 15 on both sides

4(2x- 5) =  - 4

Divide 4 on both sides

2x - 5 = -1

2x = 4

Divide both sides by 2

X = 2

Hope this helps ;P

I enede up getting 3.875 as the x but I'm not sure if this is right becasue when I check the soloution I ened up with 26

What I did was apply the distrubitive property normally

then added twenty to eleven divided it by 8 so I beilieve when it comes around here I hit my problem I don't think I'm doing something rght after the disributive properety?

4(2x-5) + 15 = 11

8x - 20 + 15 = 11

8x - 5 = 11

8x = 11 + 5

8x = 16

x = 16/8

x = 2

Doubke checking my work:

4(4-5) + 15  = 11

4(-1) + 15 = 11

-4 + 15 = 11

11 = 11

Therefore, x = 2.

I guess my question is how did the -20 become a five?

Or are you saying you added 15 to the -20 then did the rest?

Yes he added 15 to -20 to get -5. There are different ways to do this problems the Guests way or my way or another way.
