Answer:
1. x = 7
2. x = 9
Step-by-step explanation:
1. 3(2x + 4) = 54
Multiply 3 by the numbers in “( )”
6x + 12 = 54
Subtract 12 from both sides
6x = 42
x = 42/6
x = 7
****************************************
2. 4 + (5x + 5) = 54
Subtract 4 from both sides
5x + 5 = 50
Subtract 5 from both sides
5x = 45
x = 45/5
x = 9
