    3y-7x=35 how do you solve this equation

    In order to answer this question there needs to be a value for either x or y.  Or, you need to ask the whole question asked, there is something missing in this question in order for someone to help come up with an answer.

    3y-7x=35
    3y=35 + 7x        (Add 7x to both sides)
    3y=35 + 7           (Let x = 1 to eliminate x from the equation)
    3y= 42                 (Add 35 + 7)
    y= 42/3 = 14     (Divide by 3 on both sides)

    Therefore 3(14) - 7(1) = 35

    The question is incomplete. You should mention the range of x and y

    3y - 7x = 35
    or, 3y = 35 +7x
    or, y = (35 + 7x)/3

    Now, if x = 0 , y = 35/3
    Now, if x=1, y = 42/3 i.e 14

    Now if x = 2,3, 4.......................... or ........... -3,-2,-1 we will get different value of y.

    There can be infinitely many solution.

    Actually, the best way to answer this question would be to graph the result.  Just like creation75 said, there are infinite answers. 

    The graph for this solution would be a straight diagonal line extending at both ends to infinity, said line crossing the x-axis at y=0 and x= -5 and it would cross the y axis at x=0 and y=35/3 (or about 11.67).  Every point on that line would be a solution for the equation.

    This question comes under the concept of Special Eqations.... there are possibly infinite solutions..... You will need another statement or any range in addition to the equation to determine a unique answer for this  kind of special equations....... 

    3y - 7x = 35

    or, 3y = 35 +7x

    or, y = (35 + 7x)/3

    Now, if x = 0 , y = 35/3

    Now, if x=1, y = 42/3 i.e 14

    Now if x = 2,3, 4........ or ...... -3,-2,-1 we will get different value of y.

    This is incomplete question.There must be atleast two equations to find two unknowns X and Y. OR you must define the range of X or Y.
