Solve -4x+15*4*2-225*2=0

$$-4x+15 \times 4 \times 2-225 \times 2=0$$

Solve for x

$$x = -\frac{165}{2} = -82\frac{1}{2} = -82.5$$

Steps for Solving Linear Equation

Multiply 15 and 4 to get 60.

$$-4x+60\times 2-225\times 2=0$$

Multiply 60 and 2 to get 120.

$$-4x+120-225\times 2=0$$

Multiply 225 and 2 to get 450.

$$-4x+120-450=0$$

Subtract 450 from 120 to get -330.

$$-4x-330=0$$

Add 330 to both sides. Anything plus zero gives itself.

$$-4x=330$$

Divide both sides by -4.

$$x=\frac{330}{-4}$$

Reduce the fraction \frac{330}{-4} to lowest terms by extracting and canceling out 2.

$$x=-\frac{165}{2}$$
