Answer:
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] 4x = 5y - 3
[2] x = 5y/4 - 3/4
// Plug this in for variable x in equation [1]
[1] 3•(5y/4-3/4) + 5y = -11
[1] 35y/4 = -35/4
[1] 35y = -35
// Solve equation [1] for the variable y
[1] 35y = - 35
[1] y = - 1
// By now we know this much :
x = 5y/4-3/4
y = -1
// Use the y value to solve for x
x = (5/4)(-1)-3/4 = -2
