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

    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

    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| Getting @rannsan

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