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
Let the x's be -3 and the y's be 4 and solve for m and b.
5(-3)+7(4)=b
-15+28=b
highlight%2813=b%29
m(-3)+4=22
-3m+4-4=22-4
-3m=18
-3m/-3=18/-3
highlight%28m=-6%29
Happy Calculating!!!
