Question

$$10 y = 81 - \frac { 9 } { 20 }$$

Solve for y

$y = \frac{1611}{200} = 8\frac{11}{200} = 8.055$

Steps for Solving Linear Equation

Convert $81$ to fraction $\frac{1620}{20}$.

$$10y=\frac{1620}{20}-\frac{9}{20}$$

Since $\frac{1620}{20}$ and $\frac{9}{20}$ have the same denominator, subtract them by subtracting their numerators.

$$10y=\frac{1620-9}{20}$$

Subtract $9$ from $1620$ to get $1611$.

$$10y=\frac{1611}{20}$$

Divide both sides by $10$.

$$y=\frac{\frac{1611}{20}}{10}$$

Express $\frac{\frac{1611}{20}}{10}$ as a single fraction.

$$y=\frac{1611}{20\times 10}$$

Multiply $20$ and $10$ to get $200$.

$$y=\frac{1611}{200}$$
