Put in function form. 8X - 7Y = 168 - 7Y = - 8X + 168 Y = 8/7X - 24 0 out Y 8/7X - 24 = 0 8/7X = 24 X = 21 ---------- 0 out X Y = - 24 ----------- (21,-24) X and Y intercepts.
It is: 8+7y
7y-8 = 6y+1 7y-6y = 1+8 y = 9
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
Well, honey, if 7y + 8 is equal to 57, then you just need to do a little math dance to solve for y. Subtract 8 from both sides to get 7y = 49, then divide by 7 to find y = 7. So, if 7y + 8 equals 57, then 2y would be 14. Hope that clears things up for ya!
