Solve the equation.
31 + 2x = 243
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
start with:
31 + 2x = 243
subtract 31 from both sides of this equation to get:
31 + 2x - 31 = 243 - 31
simplify by combining like terms to get:
2x = 212
divide both sides of this equation by 2 to get:
2x/2 = 212/2
simplify by performing the indicated operations to get:
x = 106.

confirm by replacing x with 106 in your original equation.

31 + 2x = 243 becomes:
31 + 2*106 = 243 which becomes:
31 + 212 = 243 which becomes:
243 = 243 confirming the solution is good.
