Answer:

The solution to the system is:

x = -63

y = 10

Explanation:

Given the pair of equations:

x + 3y = -33 ......................................................(1)

-4x + 5y = -38 ...................................................(2)

Multiply (1) by 4

4x + 12y = -132 ..................................................(3)

Add (2) and (3)

-4x + 4x + 5y + 12y = -38 - 132

17y = 170

Divide both sides by 17

y = 170/17 = 10

Substitute y by 10 in (1)

x + 3(10) = -33

x + 30 = -33

Subtract 30 from both sides

x = -33 - 30

x = -63

Therefore,

x= -63, y = 10
