-9t + 2 = 56

Question

To solve equations of the form ax + b = c

Answer 1

-9t +2 = 56

 

subtract 2 from both sides.            Test if -6 plugged into original equation.

                                                      

                                                      -9(-6) + 2   = 54

  -9t + 2 - 2 = 56 -2

                                                       54 +2 =

    -9t = 54

                                                         56 = 56     

       t = -6

    

      

Answer 2

Subtract 2 from both sides:

-9t=54

Divide both sides by −9:

t=54/-9 which equals −6

thus, t = -6

Answer 3

-9t + 2 = 56

 

Subtract 2 from each side

 

-9t +2 (-2) = 56 -2

-9t = 54, divide by -9 on each side

t = -6

 

The trick to the ax + b = c is to add or subtract b to both sides (depending on the sign) and divide by (a) to get x by itself.
