The most efficient method of solving the equation was substitution. It was easy because we just had to substitute the variables with a smaller, easier equation. This equation would take L's place, and after multiplying 2 by -L and 10 in the equation, I solved using the reverse of Pemdas. (L+20=24) would be solved as (L+(20-20)=24-20. L=4. Then, 4 is plugged in for L in the first original equation. 2s+3L=24, 2s+3(4)=24. 2s+12=24. 12-12=0. 24=12=12. 2s=12. divide both sides by 2. s=6.
