Answer:
-39
Step-by-step explanation:
Substitute x by - 3 and y by 4
(-3)^3 - 3 *4 = - 39
18 and 54
Make y the subject:
y = 6 - x
Now, use Elimination.
0 = 3x - 3
Divide both sides by 3:
0 = x - 1
So x = 1.
Substitute back into the equation:
y = 6 - (1)
So y = 5.
Hence, the answers are x = 1, y = 5.
