Solve each equation
1.X+9=12
2.s- 1=10
3.3=z-11

Answer 1

1. Subtract 9 from both sides to get X=3
2. Add 1 to both sides to get S =11
3. Add 11 to both sides to get Z=14

Answer 2

Answer: 1.) x+9=12

                 Sol ?

               or, x=12-9

               or, x=3

               2.) s-1=10

                  Sol ?

                or, s = 10+1

                or, s=11

               3.) 3 = z-11

                 Sol ?

                or, 3+11 = z

                or, 14 = z
