Commutative Property

1-2 step equations

100

Solve the equation and check the solution:

-7m = 63

-7m = 63                -7(-9)=63

m=-9                          63 = 63

                                     true

200

Solve the equation and check the solution:

n/7 = -8

n/7 = -8                     (-56)/7 = -8

n= -56                              -8 = -8

                                         true

300

Solve the equation and check the solution:

-2k-4=8

-2k - 4 = 8                   -2(-6) - 4 = 8

k=-6                                 12 - 4 = 8

                                               8 = 8

                                                true

400

Solve the equation and check the solution:

h/-3 + 6 = -4

h/-3 + 6 = -4               (30)/-3 + 6 = -4

h=30                            -10 + 6 = -4

                                        -4 = -4

                                           true

500

Solve the equation and check the solution:

2x + 6 = 6

2x + 6 = 6                     2(0) + 6 = 6

x = 0                                       6 = 6

                                              true
