You can put this solution on YOUR website! (x+84)/70= (x-29)/61
Cross-multiply
(x+84)*61=(x-29)*70
61x+5124=70x-2030
7154=9x
x=794 8/9=794.89
======
794.888+84=878.888.
Divide by 70=12.555
765.89/61=12.555
x=794 8/9
First, render your equation in plain text like this:
(x + 84)/(70) = (x - 29)/(61).
That we understand; the mess you made, not so much. One more thing: X and x are two different things; be consistent with your capitalization.
Second, this is a proportion, so cross multiply: Numerator on the left times denominator on the right is equal to denominator on the left times numerator on the right. That gives you a linear equation in that can be solved by ordinary means.
