# How do you solve #z- - 797= 977#?

##### 1 Answer

#### Answer:

#### Explanation:

So first you simplify the left-hand side of the equation by simplifying

#z - (-797)#

into

#z + 797#

The equation at this point is

#z + 797 = 977#

You subtract

#z + cancel(797) - cancel(797) = 977-797#

The

#z = 977-797#

which gives you

#z = 180#
