7y + 4(92 - 9) = 87 + 67y(10 + 23)
7y + 4(83) = 87 + 67y(33)
7y +332 = 87 + 2211y
7y + 332 - 7y = 87 + 2211y - 7y
332 = 87 + 2204y
332 - 87 = 87 +2204y - 87
245 = 2204y
245/2204 = 2204y/2204
245/2204 = y

7y+4(92-9)=87+67y(10+23)
7y + (4*83) = 87 + (67y)(33)
7y + 332 = 87 + 2211y
7y - 2211y = 87 - 332
-2204y = -245
2204y = 245
y = 245/2204

7y+4(92-9)=87+67y(10+23) first, you do everything in the parenthesis
7y+4(83)=87+67y(33) then you do all the multiplication
7y+332=87+2211y then you subtract 7y from both sides
332=87+2204y then you subtract 87 from both sides
245=2204y then divide both sides by 2204
y=.111161524....

1) 7y+324 =87+2211y
2) 332 -87 = 2211y-7y
3) 245 = y(2211-7)
4) 245 = y(2204)
5) 245/2204 = y
6) y= 0.111
