Solve n-4(175+x)=18

$$n - 4 ( 175 + x ) = 18$$

Solve for n

$$n=4x+718$$

Solution Steps

Use the distributive property to multiply -4 by 175+x.

$$n-700-4x=18$$

Add 700 to both sides.

$$n-4x=18+700$$

Add 18 and 700 to get 718.

$$n-4x=718$$

Add 4x to both sides.

$$n=718+4x$$

Solve for x

$$x=\frac{n-718}{4}$$

Steps for Solving Linear Equation

Use the distributive property to multiply -4 by 175+x.

$$n-700-4x=18$$

Subtract n from both sides.

$$-700-4x=18-n$$

Add 700 to both sides.

$$-4x=18-n+700$$

Add 18 and 700 to get 718.

$$-4x=718-n$$

Divide both sides by -4.

$$\frac{-4x}{-4}=\frac{718-n}{-4}$$

Dividing by -4 undoes the multiplication by -4.

$$x=\frac{718-n}{-4}$$

Divide 718-n by -4.

$$x=\frac{n}{4}-\frac{359}{2}$$
