Hi, 

Let x represent the number Of washers the second machine can produce in one hour

Then 2x is the number Of washers  the first machine can produce in one hour

Write as we Read

2hr *2x/hr + 3hr*x/hr = 560 washers

solve for x

4x + 3x = 560

7x = 560

x = 80, number Of washers the second machine can produce in one hour

(2*80) Or 160 is number Of washers the first machine can produce in one hour



checking our answer

2*160 + 3*80 = 560
