2y - x = 3

y = -5x + 7

Rewrite the second

y + 5x = 7

Mutiply it by 2

2y + 10x = 14

Now subtract the first equation from this:

2y + 10x = 14

2y - x = 3

11x = 11

Divide both sides by 11: x = 1

Substitute for x in the first equation:

2y - 1 = 3

Add 1 to both sides: 2y = 4

Divide both sides by 2: y = 2

Answer: (x, y) = (1, 2)

Q: What is the solution of 2y-x equals 3 and y equals -5x plus 7?

x = -5

-5x=3+y x=-1/5y-3/5

yes there is.-5x+1=-10-5x=-11-x=-11/5x=11/5

x=-2, y=2

That equation has no solution. There is no possible number that's equal to 18 more than itself.
