Solve {88-(5*x+57)}div4/5=20

$$\{ 88 - ( 5 \times x + 57 ) \} \div \frac { 4 } { 5 } = 20$$

Solve for x

$$x=3$$

Steps for Solving Linear Equation

Multiply both sides by \frac{4}{5}.

$$88-\left(5x+57\right)=20\times \frac{4}{5}$$

To find the opposite of 5x+57, find the opposite of each term.

$$88-5x-57=20\times \frac{4}{5}$$

Subtract 57 from 88 to get 31.

$$31-5x=20\times \frac{4}{5}$$

Express 20\times \frac{4}{5} as a single fraction.

$$31-5x=\frac{20\times 4}{5}$$

Multiply 20 and 4 to get 80.

$$31-5x=\frac{80}{5}$$

Divide 80 by 5 to get 16.

$$31-5x=16$$

Subtract 31 from both sides.

$$-5x=16-31$$

Subtract 31 from 16 to get -15.

$$-5x=-15$$

Divide both sides by -5.

$$x=\frac{-15}{-5}$$

Divide -15 by -5 to get 3.

$$x=3$$
