74-34=20 so then y=20 because 20*2+34=74
IN other words
74-34=20

we needed to eliminate w, do so by diving both sides by w and obtain the above result :)
Hope this helps.
Answer:
to put in the value of any variable in this equation(for example 2 ) we will write it as

g(2) = 8 - 16 + 14 - 8
g(2) = -2
