Answer:
Step-by-step explanation: Perform any simplification of like terms if possible
7x=3x+16
Collect x terms on one side. Can use the left side for x terms. That means 3x must dissapear. To do this we need to take 3x from both sides.
7x-3x=3x-3x+16
4x=16
To solve for x we need to divide by 4 on both sides
4x/4=16/4
x=4
