To solve an equation, you need to isolate the variable using inverse operations.
For −11+Z=7, you have −11 being added to Z. The inverse operation of addition is subtraction, so you need to subtract −11 on both sides:
-11+Z=7
−11+Z−11+Z−(−11)=7=7−(−11)
Subtacting a negative number is the same as adding a positive number so you can simplify the equation to:
−11+Z−(−11)=7−(−11)
-11+Z+11=7+11
Simplifying then gives:
−11+Z+11=7+11
Z=7+11=18
The solution of the equation is then Z=18
