Question

Solve using substitution
y=2
x+10y=17

answer is an ordered pair

Answer 1

(- 3, 2 )

Explanation:

y = 2 → (1)

x + 10y = 17 → (2)

Substitute y = 2 into (2)

x + 10(2) = 17

x + 20 = 17 ( subtract 20 from both sides )

x = - 3

solution is (- 3, 2 )

Answer 2

x = -3

Explanation:

x+10y=17

x+10(2)=17

x+20=17

- 20 - 20

-----------------

x = -3

the ordered pair is x=-3, y=2, (-3,2)
