Question

Please solve the equations below. Explain. 3x-4=x 2x-4=x

Answer 1

10Step 1: Subtract x from both sides.3x−4−x=x−x2x−4=0Step 2: Add 4 to both sides.2x−4+4=0+42x=4Step 3: Divide both sides by 2.2x2=42x=2 

2)Step 1: Subtract x from both sides.2x−4−x=x−xx−4=0Step 2: Add 4 to both sides.x−4+4=0+4x=4

Answer 2

Well, lets solve by combing like terms.
For the first it would be:
2x=4
The second would be:
x=4
So for #1 x=2 and #2 x=4

Hope this helps!
