Answer:
x=4
Step-by-step explanation:
3x+x−2x+8=3x+x
Step 1: Simplify both sides of the equation.
3x+x−2x+8=3x+x
3x+x+−2x+8=3x+x
(3x+x+−2x)+(8)=(3x+x)(Combine Like Terms)
2x+8=4x
2x+8=4x
Step 2: Subtract 4x from both sides.
2x+8−4x=4x−4x
−2x+8=0
Step 3: Subtract 8 from both sides.
−2x+8−8=0−8
−2x=−8
Step 4: Divide both sides by -2.
−2x−2=−8−2
x=4
