Question

Use the substitution method to solve the following system of equations.

Choose the ordered pair that is a solution to this system of equations:

3x + y = 5
4x + 5y = 3

(1, -1)

(1, -2)

(1, 2)

(2, -1)

(2, 1)

Answer 1

these questions are all over the map
is this some sort of on line course?

Answer 2

answer is x = 2, y = -1 but i am not sure how this relates to previous questions

Answer 3

3x + y = 5
4x + 5y = 3

y = 5 - 3x
4x + 5(5 - 3x )= 3
x = 2,

2*2 + y = 5
y = -1
