-40=-8(x+2) solve the equation

x = 3

Step-by-step explanation:

-40 = -8 (x + 2)

-8 (x + 2) = -40   --- divide both sides by - 8

-8 (x + 2)           -40

  =  

      -8                  -8

x + 2 = 5    --- subtract 2 from both sides

x + 2 - 2 = 5 - 2   then simplify

x = 3

x=3

Step-by-step explanation:

First, write out the equation as you have been given it:

Then distribute the -8 to the terms inside the parenthesis:

Next, add 16 to both sides:

Finally, divide both sides by -8:

Therefore, x=3.
