Solve 90/x*1.9=5.8

$$90 / x \times 1.9 = 5.8$$

Solve for x

$$x = \frac{855}{29} = 29\frac{14}{29} \approx 29.482758621$$

Steps for Solving Linear Equation

Divide both sides by 1.9.

$$\frac{90}{x}=\frac{5.8}{1.9}$$

Expand \frac{5.8}{1.9} by multiplying both numerator and the denominator by 10.

$$\frac{90}{x}=\frac{58}{19}$$

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 19x, the least common multiple of x,19.

$$19\times 90=58x$$

Multiply 19 and 90 to get 1710.

$$1710=58x$$

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

$$58x=1710$$

Divide both sides by 58.

$$x=\frac{1710}{58}$$

Reduce the fraction \frac{1710}{58} to lowest terms by extracting and canceling out 2.

$$x=\frac{855}{29}$$
