Solve (280:x)+60=80

$$( 280 : x ) + 60 = 80$$

Solve for x

$$x=14$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.

$$280+x\times 60=80x$$

Subtract 80x from both sides.

$$280+x\times 60-80x=0$$

Combine x\times 60 and -80x to get -20x.

$$280-20x=0$$

Subtract 280 from both sides. Anything subtracted from zero gives its negation.

$$-20x=-280$$

Divide both sides by -20.

$$x=\frac{-280}{-20}$$

Divide -280 by -20 to get 14.

$$x=14$$
