Question

How do you solve -9( -4r + 6s ) + 3s - 7(6s - 2r)

Answer 1

Answer: 2.1 Pull out like factors :

6s - 2r  =   -2 • (r - 3s)

Equation at the end of step

 ((0-(9•(6s-4r)))+3s)--14•(r-3s)

Pulling out like terms

4.1     Pull out like factors :  6s - 4r  =   -2 • (2r - 3s)

Equation at the end of step

 ((0--18•(2r-3s))+3s)--14•(r-3s)

Final result :

 50r - 93s
