Question

1. Which of the following pairs of equations has (5,3) as a solution?

a. x-y=2 b. y-x = -2 c. 2x+3y=-7 d. x+ y = 8
4x = 5y +5 x-15 = -y x + y = 23 3x+3y = 9

Answer 1

a, b, d, 4x=5y+5

Explanation:

Plug in x and y values to equations.

a: 5-3=2 - correct

b: 3-5=-2 - correct

c: 2(5) + 3(3)= -7 - incorrect

d: 5+3=8 - correct

e?: 4(5) = 5(3)+5 - correct

f?: 5-15= -3 - incorrect

g?: 5+3=23 - incorrect

h?- 3(5) + 3(3) = 9

hope this helped!
