Ответ:
A
Step-by-step explanation:
So we have the equation:
On the right combine like terms:
Subtract 18 from both sides. The right cancels:
Divide both sides by 3:
The answer is A, -11.
Ответ:
a = -11
Step-by-step explanation:
-15 = 5a +12- 2a + 6
Combine like terms
-15 = 3a +18
Subtract 18 from each side
-15-18 = 3a+18-18
-33 = 3a
Divide each side by 3
-33/3 = 3a/3
-11 =a
