Question 206055: What are the steps to turn this equation 1.50x+1.25y=375 into an equation you can graph?
so far i have
1.50x+1.25y=375
-1.50x -1.50x
1.25y=375-1.50x
and now i dont know what else to do or if im even on the right track.

Question 206054: Your company produces two models of bicycles: Model A and Model B. Model A takes 2 hours to assemble, where Model B takes 3 hours to assemble. Model A costs $25 to make per bike where Model B costs $30 to make per bike. If your company has a total of 34 hours and $350 available per day for these two models, how many of each model can be made in a day?
Solve using Elimination Method:
Equation:
120x+180y = 21,600 hours assembling per day
$25x+$30y = $750 costs
first equation:
120x + 180y = 21,600
second equation
(-5) 25 + (-5) 30y = (-5) 750
elimination 245x + 330y = -17,850
substitute back in to equation
120x + 180y ( ) = 21,600

x = bikes per day
I need help solving this equation with the steps
