Question

Please help!

solve for y.
x+2y=5

Answer 1

subtract x from both sides, then divide both sides by 2

Answer 2

is it 2.5?

Answer 3

y=5+x/2

Answer 4

how will I be able to write this answer in this format?

y=(_)/_

Answer 5

see the question is solve for y therefore we have to find the value of y in terms of x

Answer 6

so shift everything except y to the right!

Answer 7

i dont get it.

Answer 8

We need to solve for y, but we can't COMPLETELY solve for y unless we know x too.
x+2y=5 ---Subtract x from both sides
2y=-x+5 ---Divide everything by 2
y = -1/2x +5/2

Does this make sense?

Answer 9

yes so i just have to solve it now?

Answer 11

Well...you have already solved for y, because we have
y = something
Think about it this way. When we usually solve for y, we have something like
y = 6
It doesn't necessarily have to be a number though, the solution could be
y = 2x-z-9+r+w
It doesn't matter, as long as we have y = something.
