Given data:
The first equation is 3j +14=-5z.
The second equation is -10j=5z .
Add both the equations.

Substitute 2 for j in the first equation.

Thus, the value of j is 2 and z is -4.
Now what you want to do is 21 + (-3). Since this is the same as saying 21 - 3, the answer is 18. Therefore, the answer is 18°F.
