Solve 10.5/3x=4.2

$$\frac { 10.5 } { 3 x } = 4.2$$

Solve for x

$$x=\frac{5}{6}\approx 0.833333333$$

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 3x.

$$10.5=12.6x$$

Swap sides so that all variable terms are on the left hand side.

$$12.6x=10.5$$

Divide both sides by 12.6.

$$x=\frac{10.5}{12.6}$$

Expand \frac{10.5}{12.6} by multiplying both numerator and the denominator by 10.

$$x=\frac{105}{126}$$

Reduce the fraction \frac{105}{126} to lowest terms by extracting and canceling out 21.

$$x=\frac{5}{6}$$
