Answer:
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] 4x = 24
[2] x = 6
// Plug this in for variable x in equation [1]
[1] 5•(6) + 8y = 14
[1] 8y = -16
// Solve equation [1] for the variable y
[1] 8y = - 16
[1] y = - 2
// By now we know this much :
x = 6
y = -2
We are done {x,y} = {6,-2}
