Solve (3+x):x=4:1

$$( 3 + x ) : x = 4 : 1$$

Solve for x

$$x=1$$

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.

$$3+x=x\times 4$$

Subtract x\times 4 from both sides.

$$3+x-x\times 4=0$$

Combine x and -x\times 4 to get -3x.

$$3-3x=0$$

Subtract 3 from both sides. Anything subtracted from zero gives its negation.

$$-3x=-3$$

Divide both sides by -3.

$$x=\frac{-3}{-3}$$

Divide -3 by -3 to get 1.

$$x=1$$
