Question

Consider this system of linear equations:

y − x = -13
-4x + 3y = -51
The solution of the system of equations is

Answer 1

(x, y) = (12, -1)

Explanation:

Answer 2

-x + y = -13 → -3x + 3y = -39
-4x + 3y = -51 → -4x + 3y = -51
x = 12
-x + y = -13
-(12) + y = -13
-12 + y = -13
+ 12 + 12
y = -1
(x, y) = (12, -1)
