Solve -30*2-30*4+6x-18.75*8=0

$$-30 \cdot 2-30 \cdot 4+6x-18.75 \cdot 8 = 0$$

Solve for x

$$x=55$$

Steps for Solving Linear Equation

Multiply -30 and 2 to get -60.

$$-60-30\times 4+6x-18.75\times 8=0$$

Multiply 30 and 4 to get 120.

$$-60-120+6x-18.75\times 8=0$$

Subtract 120 from -60 to get -180.

$$-180+6x-18.75\times 8=0$$

Multiply 18.75 and 8 to get 150.

$$-180+6x-150=0$$

Subtract 150 from -180 to get -330.

$$-330+6x=0$$

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

$$6x=330$$

Divide both sides by 6.

$$x=\frac{330}{6}$$

Divide 330 by 6 to get 55.

$$x=55$$
