Solve (x+x-5)*12/2=450

$$\frac { ( x + x - 5 ) \cdot 12 } { 2 } = 450$$

Solve for x

$$x=40$$

Steps for Solving Linear Equation

Multiply both sides by 2.

$$\left(x+x-5\right)\times 12=450\times 2$$

Combine x and x to get 2x.

$$\left(2x-5\right)\times 12=450\times 2$$

Use the distributive property to multiply 2x-5 by 12.

$$24x-60=450\times 2$$

Multiply 450 and 2 to get 900.

$$24x-60=900$$

Add 60 to both sides.

$$24x=900+60$$

Add 900 and 60 to get 960.

$$24x=960$$

Divide both sides by 24.

$$x=\frac{960}{24}$$

Divide 960 by 24 to get 40.

$$x=40$$
