Answer:
x : -3
Step-by-step explanation:
1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)
2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)
3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)
4) -6x = 18 (divide the -6 on both sides)
5) x = -3
I believe the answer is C. It is the only one that makes sense
Whats the question? not really understanding what your asking?
Answer:
x = -24
a = 11
Step-by-step explanation:
So for the first one:
Multiply both sides of the equation by 12
Subtract 8x from both sides
Subtract 72 from both sides
Divide both sides by -11
And the second one...
Distribute the 2 to the (a - 2) and the 3 to (a - 5)
then add 15 to both sides
Subtract 2a from both sides
11 = a
