how do i complete the problem
Distribute: 66= -6a -12a -6
Combine Like Terms: 66 = -18a -6
Add 6 to both sides: 72= -18a
Divide: a = -4
66 = -6a - 6(2a + 1)
66 = -6a -12a -6
66 = -18a - 6
+6 +6
72 = -18a
(divide by -18)
-4 = a
distribute six so it looks like 66=-6a-12a+6 then ad a's so it is 66=6a+6 subtract 6 from both sides
6a=60 divide by six and a=10
multiply -6 with (2a+1) : -6(-2a) is -12a and -6(1) is -6
66=-6a-12a-6
combine like terms
66=-18a-6
add six on both sides to have the variable on one side
72=-18a
divide both sides by -18
-4=a
the answer is -4
