Question

For what numbers a and b is the system of equations below satisfied by x=b and y=a?
x-4y =a
3x +y= 96
b=___________? a=________________?

Answer 1

line didnt work on the other problem either direct

Answer 2

b - 4a = a
3b + a = 96

b = 5a

3(5a) + a = 96
15a + a = 96
16a = 96
a = 96/16
a = 6
b = 30

Answer 3

The first step is to replace x with b and y with a, then solve.
