solve for x: 5/3x = 25

To solve for x, we can follow these steps:

Step 1: Multiply both sides of the equation by 3 to eliminate the fraction:
3 * (5/3x) = 3 * 25

This simplifies to:
5x = 75

Step 2: Divide both sides of the equation by 5 to isolate x:
5x/5 = 75/5

This simplifies to:
x = 15

Therefore, the solution is x = 15.

solve for x: 4x/9 = 18

To solve for x, we can follow these steps:

Step 1: Multiply both sides of the equation by 9 to eliminate the fraction:
9 * (4x/9) = 9 * 18

This simplifies to:
4x = 162

Step 2: Divide both sides of the equation by 4 to isolate x:
4x/4 = 162/4

This simplifies to:
x = 40.5

Therefore, the solution is x = 40.5.
