Solve z/12 - 13/12 =18/12

Evaluate

\frac{z}{12} - \frac{13}{12} = \frac{18}{12}

Cancel out the common factor 6

\frac{z}{12} - \frac{13}{12} = \frac{3}{2}

Move the constant to the right-hand side and change its sign

\frac{z}{12} = \frac{3}{2} + \frac{13}{12}

Add the numbers

More Steps

\frac{z}{12} = \frac{31}{12}

Multiply both sides of the equation by 12

\frac{z}{12} \times 12 = \frac{31}{12} \times 12

Solution

z = 31
