Solve x-4+2x+18.2+x+4+1x+25.5=90

$$x-4+2x+18.2+x+4+1x+25.5 = 90$$

Solve for x

$$x=9.26$$

Steps for Solving Linear Equation

Combine x and 2x to get 3x.

$$3x-4+18.2+x+4+1x+25.5=90$$

Add -4 and 18.2 to get 14.2.

$$3x+14.2+x+4+1x+25.5=90$$

Combine 3x and x to get 4x.

$$4x+14.2+4+1x+25.5=90$$

Add 14.2 and 4 to get 18.2.

$$4x+18.2+1x+25.5=90$$

Combine 4x and 1x to get 5x.

$$5x+18.2+25.5=90$$

Add 18.2 and 25.5 to get 43.7.

$$5x+43.7=90$$

Subtract 43.7 from both sides.

$$5x=90-43.7$$

Subtract 43.7 from 90 to get 46.3.

$$5x=46.3$$

Divide both sides by 5.

$$x=\frac{46.3}{5}$$

Expand \frac{46.3}{5} by multiplying both numerator and the denominator by 10.

$$x=\frac{463}{50}$$
