Answer 1

Answer:

960,840

Step-by-step explanation:

x+y=1800

y=1800-x

-------------

3x/16+2y/7=420

3x/16+2y/7=420

21x+32y/112=420

21x+32y=420×112

21x+32y=47040

21x+32 (1800-x)=47040

21x+57600-32x=47040

11x=10560

x=960

------------

x+y=1800

960+y=1800

y=1800-960

y=840

----------

x=960

y=840
