7x- 3(x- 6) = 30
A. X=3
B.x=9
C.x=6
D.x=12

Answer:
x=3
Step-by-step explanation:
1. Simplify the expression
7x-\left(3\cdot\left(x-6\right)\right)=30
Solve by distributing:
7x-\left(3x+3\cdot-6\right)=30
Simplify the arithmetic:
7x-\left(3x-18\right)=30
Expand the parentheses:
7x-3x+18=30
Simplify the arithmetic:
4x+18=30
