12/x=21/x+12-এর সমাধান করুন

$$\frac { 12 } { x } = \frac { 21 } { x + 12 }$$

Solve for x

$$x=16$$

Steps for Solving Linear Equation

Variable x cannot be equal to any of the values -12,0 since division by zero is not defined. Multiply both sides of the equation by x\left(x+12\right), the least common multiple of x,x+12.

$$\left(x+12\right)\times 12=x\times 21$$

Use the distributive property to multiply x+12 by 12.

$$12x+144=x\times 21$$

Subtract x\times 21 from both sides.

$$12x+144-x\times 21=0$$

Combine 12x and -x\times 21 to get -9x.

$$-9x+144=0$$

Subtract 144 from both sides. Anything subtracted from zero gives its negation.

$$-9x=-144$$

Divide both sides by -9.

$$x=\frac{-144}{-9}$$

Divide -144 by -9 to get 16.

$$x=16$$
