1. Consider this system of equations.
3x + 5y = 7
2x -y =9

{x,y} = {4,1}

Step-by-step explanation:

i think this is right

x = 4

y = -1

Step-by-step explanation:

3x + 5y = 7

5(2x - y = 9). = 10x - 5y = 45 (add the equations)

13x = 52. X = 4

3 (4) + 5y = 7

12 + 5y = 7

5y = 7 - 12

y = -5/5. y = -1

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

i can answer this question sweetie!
