On the solution of the equation of first degree with one variable Some of the same rooms need to be painted. Three first-class technicians go to paint eight rooms a day. As a result, 50 square meters of the wall will have to be painted in the future. In the same time, five second-class technicians paint another 40 square meters of the wall in addition to 10 rooms. Each first-class technician paints 10 square meters of the wall in one day more than the second-class technician, so the wall area of each room needs to be painted
The area of the wall to be painted in each room is x square meters
8x-50/3=10x+40/5+10
40x-250=30x+120+150
10x=520
x=52
Answer: each room needs to paint the wall area is 52 square meters
