Solve 15=4*100/45+x

$$15 = \frac { 4 \times 100 } { 45 + x }$$

Solve for x

$$x = -\frac{55}{3} = -18\frac{1}{3} \approx -18.333333333$$

Steps for Solving Linear Equation

Variable x cannot be equal to -45 since division by zero is not defined. Multiply both sides of the equation by x+45.

$$15\left(x+45\right)=4\times 100$$

Use the distributive property to multiply 15 by x+45.

$$15x+675=4\times 100$$

Multiply 4 and 100 to get 400.

$$15x+675=400$$

Subtract 675 from both sides.

$$15x=400-675$$

Subtract 675 from 400 to get -275.

$$15x=-275$$

Divide both sides by 15.

$$x=\frac{-275}{15}$$

Reduce the fraction \frac{-275}{15} to lowest terms by extracting and canceling out 5.

$$x=-\frac{55}{3}$$
