'Solve for y' means that you have to clear 'y' from the equation:


y+2x=5

Clearing 'y':


y=5-2x

Now, to find the value of 'y' for each value of 'x' you just have to replace 'x' in the expression above by each of the given values. This is:

For x = -1


y=5-(2*(-1))
y=5+2=7

When x = -1, y = 7.

For x = 0:


y=5-(2*0)
y=5-0=5

When x = 0, y = 5

For x = 3:


y=5-(2*3)
y=5-6=-1

When x = 3, y = -1
