Question

Solve the equation for y. Then find the value of y for each value of x.
2x-5y=19; x=1,0,1
Solve equation for y.

Answer 1

So you have to bring 5y to the opposite side to make it positive and then 19 to the other side to isolate 5y and then divide both sides by 5 to get y alone. Did you get that much? After that its simply plugging in the values for x.

Answer 2

alternatively you can subtract 2x from both sides and then divide both sides by -5 which will yield the same results for y.

Answer 3

im really bad with this stuff.... show me how to solve it?

Answer 4

so you have 2x - 5y = 19
step 1:
2x - 5y - 2x = 19 - 2x (subtract 2x from both sides) yielding: -5y = 19 - 2x

step 2:

-5y / -5 = (19-2x) / -5 (divide both sides by -5 to get y alone) yielding: y = (19-2x)/(-5)

so now you have y = -(19-2x)/5 . Now all you have to to do is plug in the three values for x to get the three values for y.

make sense?

great thanks Rhystic
