Question

-2x – 1 = y
5y + 3x = 9
solve for x and y

Answer 1

Explanation:

y=-2x-1

5y+3x=9, using y from above in this equation gives you

5(-2x-1)+3x=9

-10x-5+3x=9

-7x-5=9

-7x=14

x=-2, and since y=-2x-1

y=-2(-2)-1

y=4-1=3, so the solution is the point (-2,3)

x=-2 and y=3

Answer 2

(-2,3)

Explanation:

(-2,3) hope this helps
