Question

Which ordered pair is the solution to this system of equation?

y = x - 1

x + y = 5


(-6, -1)
(-6, -1)

(7, -2)
(7, -2)

(-1, 6)
(-1, 6)

(3, 2)

Answer 1

(d) (3, -2)

Explanation:

It is easy enough to check the offered choices. All but the last fail in the first equation.

(-6, -1): -1 ≠ -6 -1

(7, -2): -2 ≠ 7 -1

(-1, 6): 6 ≠ -1 -1

(3, 2): 2 = 3 -1 . . . . . this is your solution point
