Combine like terms to get:
19x+20=10x+2
Subtract 10x+20 to get:
9x=-18
Dividing by 9, we see that:
x=-2
Therefore, -2 is the answer.

solve your equation step-by-step.
18x+20+x=5+10x−3
Simplify both sides of the equation.
18x+20+x=5+10x−3
18x+20+x=5+10x+−3
(18x+x)+(20)=(10x)+(5+−3)(Combine Like Terms)
19x+20=10x+2
Subtract 10x from both sides.
19x+20−10x=10x+2−10x
9x+20=2
Subtract 20 from both sides.
9x+20−20=2−20
9x=−18
Divide both sides by 9.
9x/9=−18/9
x=−2
