Answer:
x = -3
y = 9
Step-by-step explanation:
Add two equations up
4x + 5y - 9x - 5y = 33 - 18 add or subtract like terms
-5x = 15 divide both sides by -5
x = -3 we can use this information to find the value of y
4x + 5y = 33 replace x with -3
4 * (-3) + 5y = 33
-12 + 5y = 33 add 12 to both sides
5y = 45 divide both sides by 5
y = 9
