Question

168=18×x+12×2x
What is the value of x?
​

Answer 1

X=4

Explanation:

First you would simplify the numbers on the right which would give you 168=18x+24x. Since the two numbers have the same variable you can add them which would then give you 168=42x. Lastly you isolate the x by dividing 42 so that x=4.
