Solve x+(x+3.5)+(x+7)=28

$$x+(x+3.5)+(x+7)=28$$

Solve for x

$$x = \frac{35}{6} = 5\frac{5}{6} \approx 5.833333333$$

Steps for Solving Linear Equation

Combine x and x to get 2x.

$$2x+3.5+x+7=28$$

Combine 2x and x to get 3x.

$$3x+3.5+7=28$$

Add 3.5 and 7 to get 10.5.

$$3x+10.5=28$$

Subtract 10.5 from both sides.

$$3x=28-10.5$$

Subtract 10.5 from 28 to get 17.5.

$$3x=17.5$$

Divide both sides by 3.

$$x=\frac{17.5}{3}$$

Expand \frac{17.5}{3} by multiplying both numerator and the denominator by 10.

$$x=\frac{175}{30}$$

Reduce the fraction \frac{175}{30} to lowest terms by extracting and canceling out 5.

$$x=\frac{35}{6}$$
