Stuck on this problem

Find values for m and b in the following system so that the solution to the system is (-3,4)

5x+7y=b

mx+y=22

5(-3) + 7(4) = b

b = -15 + 28 = 13

m(-3) + 4 = 22

-3m = 22-4

m = 18/-3 = -6

Thank you Sanchi....I will use this as a template for solving my other problems like this.

no problem!
