The sixth grade mathematics first lesson exercises the second volume.
Let's assume that the workers who produce parts A and B are X and Y respectively.
Then x+y=26.
15*x/2= 10*y/3
Multiplying two sides of the second formula by 6 gives 45*x=20*y, that is, about 9*x=4*y, that is, x = 4/9 * y. Substitute this formula into the first equation, that is, 4/9*y+y=26, that is, y= 18, that is, x=8.
