\(44𝑥 = 𝑙 \)

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.

\(c={3\over 5}=0.6\)
