Solve 5*20*(1+0.2)2400/y+2400=3000

$$5 \times 20 \times (1+0.2) \frac{ 2400 }{ y } +2400=3000$$

Solve for y

$$y=480$$

Steps for Solving Linear Equation

Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y.

$$5\times 20\left(1+0.2\right)\times 2400+y\times 2400=3000y$$

Multiply 5 and 20 to get 100.

$$100\left(1+0.2\right)\times 2400+y\times 2400=3000y$$

Add 1 and 0.2 to get 1.2.

$$100\times 1.2\times 2400+y\times 2400=3000y$$

Multiply 100 and 1.2 to get 120.

$$120\times 2400+y\times 2400=3000y$$

Multiply 120 and 2400 to get 288000.

$$288000+y\times 2400=3000y$$

Subtract 3000y from both sides.

$$288000+y\times 2400-3000y=0$$

Combine y\times 2400 and -3000y to get -600y.

$$288000-600y=0$$

Subtract 288000 from both sides. Anything subtracted from zero gives its negation.

$$-600y=-288000$$

Divide both sides by -600.

$$y=\frac{-288000}{-600}$$

Divide -288000 by -600 to get 480.

$$y=480$$
