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

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
