Answer:
x=3
Step-by-step explanation:
PEMDAS
Or parenthesis, exponent, multiply, divide, addition, and subtraction. (Order of operations)
3(6-x) + 2x = 15
Start with multiplying
18 - 3x + 2x = 15
then combine like terms
18 - x = 15
subtract 18 from each side
-x = -3
times each side by -1 to remove the negative
x = 3
