Question

$$25:20=450:x$$

Solve for x

$x=360$

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 $20x$, the least common multiple of $20,x$.

$$x\times 25=20\times 450$$

Multiply $20$ and $450$ to get $9000$.

$$x\times 25=9000$$

Divide both sides by $25$.

$$x=\frac{9000}{25}$$

Divide $9000$ by $25$ to get $360$.

$$x=360$$
