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!
