x%2F%2818%29=%2819%29%2F%2818%29
Multiply both sides by 18.
x=19

%2821%29%2Fx=%2813%29%2F%2834%29
21%2A34=13%2Ax
x=%2821%2A34%29%2F13
x=714%2F13

%2812+x%29%2F%2838%29=%2850%29%2F%288%29
x=%2850%2F8%29%2838%2F12%29
x=475%2F24

%2820%29%2F%2836%29=%2836+x%29%2F%2810%29
x=%2820%2F36%29%2810%2F36%29
x=25%2F162
