$$44𝑥 = 𝑙$$

To solve for x, divide both sides by 44.

$$x={𝑙\over 44}$$

$$a-c = d-r$$

To solve for a, add c to both sides.

$$a=c+d-r$$

$$9e+4=14+8e$$

Subtract 8e from both sides.

$$e+4=14$$

Subtract 4 from both sides.

$$e=10$$

$$5c+16.5=13.5+10c$$

Subtract 10c from both sides.

$$-5c+16.5=13.5$$

Subtract 16.5 from both sides.

$$-5c=-3$$

Divide both sides by -5.

$$c={-3\over -5}$$

The negatives cancel out.

$$c={3\over 5}=0.6$$
