What is 4x+2x=x+x+20

Answer: x = 5

Step-by-step explanation:

4x+2x=x+x+20

Collect like terms to a side.

4x+2x-x-x=20

Note, the sign in front of x changes from positive to negative because the x crosses the equal sign

4x+2x-2x=20

4x=20

Divide both side by the coefficient of x

X=5

x = 5

Step-by-step explanation:

4x+2x=x+x+20

6x = 2x + 20

6x - 2x = 20

4x = 20

x = 20/4

x = 5
