Question

Nine times the sum of a number and 2 is 189. I need to make it to an equation.

Answer 1

Equation:

9(a+2)=189

Solve the equation:

9a+18=189

9a=189-18

9a=171

a=171/9

a=19

Check the solution:

Let a=19

9(a+2)=189

9(19+2)=189

171+18=189

189=189

Therefore, the equation is 9(a+2)=189 and a is 19.
