20k+10=12k
Consider the first equation. Use the distributive property to multiply 5 by 4k+2.
20k+10-12k=0
Subtract 12k from both sides.
8k+10=0
Combine 20k and -12k to get 8k.
8k=-10
Subtract 10 from both sides. Anything subtracted from zero gives its negation.
k=\frac{-10}{8}
Divide both sides by 8.
k=-\frac{5}{4}
Reduce the fraction \frac{-10}{8} to lowest terms by extracting and canceling out 2.
k=-\frac{5}{4} l=2 m=2
The system is now solved.
