If 2x + 5y = 2 and x is decreased by 5 units what happens to the value of y in units?

Question

If 2x + 5y = 2 and x is decreased by 5 units what happens to the value of y in units?

Answer 1

If we randomly assign x = 2:

2x + 5y = 2 

2(2)+ 5y = 2

4 + 5y = 2

5y = -2

Y = -.5

2x - 5x + 5y = 2 

-3(2) + 5(y) = 2

-6 + 5y = 2

5y = 8

Y = 1.6

Our y value actually goes up.

Hope this helps!
