1 3

Cross multiply:

6x * 3 = 1 * 36

Simplifying

6x * 3 = 1 * 36

Reorder the terms for easier multiplication:

6 * 3x = 1 * 36

Multiply 6 * 3

18x = 36

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '18'.

x = 2

Simplifying

x = 2
