Well what you do is move the 2x over to the other side to make y=mx+b. It should look like this: -5y=-2x+11. Then you replace the x with 2,it should now look like this: -5y=-2(2)+11. Then you simplify and get this: -5y= 7. Then you divide -5 by both sides and get: y= 1.4 or 1 2/5. Hope that helped! If this is wrong to you double check the question you wrote.
Given the equation 2x - 5y = 11 and x = 2, plug the 2 in for x and solve for y. 2(2) - 5y = 11 4 - 5y = 11 subtract 4 from both sides -5y = 7 divide both sides by -5 y = -7/5 (2, -1.4)
