Equation (1):
-8x + 4y = 24
Equation (2):
-7x + 7y = 28
Simplify the equation:
Equation 1 can be simplify by 4:
-2x + y = 6
Equation 2 can be simplify by 7:
-x + y = 4
Add x to both sides of the equation 2:
y = x + 4
Substitute equation 2 into 1:
x + 4 - 2x = 6
x - 2x = 6 - 4
- x = 2
x = - 2.
Substitute - 2 for x in equation 2:
y = - 2 + 4
y = 2.
Therefore, (x, y) = (- 2, 2)
