Answer:
A. Divide both sides of the equation by 3, and then subtract 6 from both sides of the equation. The solution is x = 1.
Step-by-step explanation:
3(x + 6) = 21
Divide both sides by 3
(x + 6) = 7
Subtract 6 from each side
x = 7-6
x=1
Answer:
x=1
Step-by-step explanation:
multiply 3 with (x+6) resulting into 3x+18=21
cross-multiply and divide through by 3.
