Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
Lennon used the property o addition
First of all why is there 2 similar equation connected to one another?
Second in order to solve this all you need to do is plug in the number and solve for x
For 485
85x+60=485
85x=420
X=5
Do the same thing and you get 3
