3x-2(6x-3)=42 *what is the value of x?
2 answers:
Answer: -4
Step-by-step explanation:
3x-2(6x-3)=42
3x - 12x + 6 = 42
-9x + 6 = 42
-9x = 42 - 6
x = -36/9 = -4
Answer:
x = -4
Step-by-step explanation:
3x-2(6x-3)=42
Distribute
3x -12x+6 = 42
Combine like terms
-9x+6 = 42
Subtract 6 from each side
-9x+6-6 = 42-6
-9x = 36
Divide each side by -9
-9x/-9 = 36/-9
x = -4
