4=3j-40
Consider the first equation. Multiply both sides of the equation by 12, the least common multiple of 3,4.
3j-40=4
Swap sides so that all variable terms are on the left hand side.
3j=4+40
Add 40 to both sides.
3j=44
Add 4 and 40 to get 44.
j=\frac{44}{3}
Divide both sides by 3.
j=\frac{44}{3} k=1 l=1 m=1
The system is now solved.
