Solve -15/x=-18/-1.5*10^9

$$\frac { - 15 } { x } = \frac { - 18 } { - 1.5 \cdot 10 ^ { 9 } }$$

Solve for x

$$x=-1250000000$$

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.

$$-15=-\frac{1}{1500000000}x\left(-18\right)$$

Express -\frac{1}{1500000000}\left(-18\right) as a single fraction.

$$-15=\frac{-\left(-18\right)}{1500000000}x$$

Multiply -1 and -18 to get 18.

$$-15=\frac{18}{1500000000}x$$

Reduce the fraction \frac{18}{1500000000} to lowest terms by extracting and canceling out 6.

$$-15=\frac{3}{250000000}x$$

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

$$\frac{3}{250000000}x=-15$$

Multiply both sides by \frac{250000000}{3}, the reciprocal of \frac{3}{250000000}.

$$x=-15\times \frac{250000000}{3}$$

Express -15\times \frac{250000000}{3} as a single fraction.

$$x=\frac{-15\times 250000000}{3}$$

Multiply -15 and 250000000 to get -3750000000.

$$x=\frac{-3750000000}{3}$$

Divide -3750000000 by 3 to get -1250000000.

$$x=-1250000000$$
