Solve x+left(x+6right)+left(x+6+6right)+left(x+6+6+6right)

$$x+ \left( x+6 \right) + \left( x+6+6 \right) + \left( x+6+6+6 \right)$$

Evaluate

$$4\left(x+9\right)$$

Solution Steps

Combine x and x to get 2x.

$$2x+6+x+6+6+x+6+6+6$$

Combine 2x and x to get 3x.

$$3x+6+6+6+x+6+6+6$$

Add 6 and 6 to get 12.

$$3x+12+6+x+6+6+6$$

Add 12 and 6 to get 18.

$$3x+18+x+6+6+6$$

Combine 3x and x to get 4x.

$$4x+18+6+6+6$$

Add 18 and 6 to get 24.

$$4x+24+6+6$$

Add 24 and 6 to get 30.

$$4x+30+6$$

Add 30 and 6 to get 36.

$$4x+36$$

Factor

$$4\left(x+9\right)$$

Solution Steps

Multiply and combine like terms.

$$4x+36$$

Factor out 4.

$$4\left(x+9\right)$$
