Solve 20left(0100-xright)+30left(xright)/80=0

$$\frac{ 20 \left( 0100-x \right) +30 \left( x \right) }{ 80 } =0$$

Solve for x

$$x=0$$

Steps for Solving Linear Equation

Multiply both sides by 80. Anything times zero gives zero.

$$20\left(0\times 100-x\right)+30x=0$$

Multiply 0 and 100 to get 0.

$$20\left(0-x\right)+30x=0$$

Anything plus zero gives itself.

$$20\left(-1\right)x+30x=0$$

Multiply 20 and -1 to get -20.

$$-20x+30x=0$$

Combine -20x and 30x to get 10x.

$$10x=0$$

Product of two numbers is equal to 0 if at least one of them is 0. Since 10 is not equal to 0, x must be equal to 0.

$$x=0$$
