subtract 2y from both sides
7x = 5 - 2y
divide both sides by 7
x = (5-2y)7
does that help?

that should be x = (5-2y)/7

7x+2y=5
Subtract the 2y on both sides
7x=-2y+5
Now divided both sides of the equation by 7
x=(-2/7)y+5/7

Let us go step by step:
Subtract 2y both the sides first..
Can you do this @rannsan

See I give you similar example:
Suppose we have:
5x+4y=10
Now subtract 4y both the sides:
|dw:1344575744194:dw|
Now to find x we must get rid of 5 attached to it so divide by 5 both the sides:
|dw:1344575819560:dw|

There I have subtracted 4y both the sides but in original question you have to subtract 2y from both the sides..
