Answer:
x = -9, y =3
Step-by-step explanation:
x + 2y = -3
x - y = -12
Subtract to two equations to eliminate x
x + 2y = -3
-x + y = 12
---------------------
3y = 9
Divide each side by 3
3y/3 = 9/3
y = 3
Now we can find x
x-y =-12
x - 3 = -12
Add 3 to each side
x-3+3 = -12+3
x = -9
Answer:
48/5
Step-by-step explanation:
6t - 20-32u
Let t= 6 and u = 1/5
6*6 - 20 -32(1/5)
Multiply
36 -20 -32/5
16 - 32/5
Get a common denominator
80/5 -32/5
48/5
