To solve this system of equations, we can first simplify the second equation:

2/3M + 1/5J = M + J Multiply through by 15 to get rid of the fractions: 10M + 3J = 15M + 15J Subtract 10M and 15J from both sides: -5M - 12J = 0

Now we have the system of equations: M + J ≤ 25 -5M - 12J = 0

To solve this system, we can first rewrite the first equation as: J ≤ 25 - M

Now we can substitute this into the second equation: -5M - 12(25 - M) = 0 -5M - 300 + 12M = 0 7M = 300 M = 300/7

Now we can substitute this back into the first equation to find J: J ≤ 25 - 300/7 J ≤ 175/7 - 300/7 J ≤ -125/7

Therefore, the solution to the system of equations is: M = 300/7 J ≤ -125/7
