1 answer:
Answer:
(-3, 1).
Step-by-step explanation:
2x + 7y = 1 -------------(A)
x + 5y = 2 Multiply this by -2:
-2x - 10y = -4 Add this equation to equation (A):
0 - 3y = -3
3y = 3
y = 1.
Substitute this in equation (A):
2x + 7(1) = 1
2x = -6
x = -3.
Check if these 2 values are correct in the second equation:
-3 + 5(1) = 2
2 = 2.
