Solve for x. -2(16 - 4x) - 8 = 6(x + 2)
Amanda [17]
So...

-2(16-4x)-8=6(x+2)             Multiply
-32+8x-8=6x+12                 Add like terms
-40+8x=6x+12                    Subtract 6x from both sides
-40+2x=12                          Add 40 to both sides
2x=52                                 Divide 2 from both sides
x=26                                   Substitute to check
-2(16-4(26))-8=6((26)+2)   Add and multiply in parenthesis
-2(-88)-8=6(28)                  Multiply
176-8=168                         Subtract
168=168                          

So x=26

I hope this helps! Have a great day!
