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
ANSWER:
Input the values x = -3 and y = 4 in the given equations.
==>5*-3 + 7*4 = b
m*-3 + 4 = 22
==> -15 + 28 = b ------------(1)
-3m + 4 = 22 -------------(2)
(1) ==> -15 + 28 = b
==> 13 = b
(2) ==> -3m = 22 -4
==> -3m = 18
Divide both sides by -3
==> -3m/-3 = 18/-3
==> m = -6
So the values are m = -6 and b = 13
Hope you understood.
