# Solve the following equations and check your results.Q.1 3x = 2x + 18

We have

3x = 2x + 18

Subtracting 2x from both sides

3x - 2x = 2x - 2x + 18

or           x = 18

Check:-  Put x = 18 in both LHS and the RHS.

LHS = 3x = 3(18) = 54

RHS =  2x + 18 = 2(18) + 18 = 36 + 18 = 54

Thus,       LHS = RHS
