Answer:
x = 29
y = 10
Step-by-step explanation:
x - 3y = -1
Add 3y to both sides;
x = 3y - 1
2x - 5y = 8
Substitute x
2x - 5y = 8
2(3y - 1) - 5y = 8
Distribute;
6y - 2 - 5y = 8
Collect like terms;
y - 2 = 8
Add 2 to both sides;
y = 10
Substitute y
x - 3y = -1
x - 3(10) = -1
x - 30 = -1
Add 30 to both sides;
x = 29
The answer would be C
Because 20 x 20 is 400 and -20 x-20 is also 400
