Question

Даю 35 балов 1)x/2-y/3-=0 x/5-x/4+1=0 2)x/3-y/4+3=0 x/2+y/5-5-=0 3)x:6+y/2-=0 x/3+y/4-4=0 4)x/5-y/3+0,6=0 x/4+y/6-1=0

Answer 1

1) {х = 2 + у, 2(2+у) - 3у + 1 = 0

{ х = 2+у, 4 + 2у - 3у + 1 = 0

{ х = 2 + у, у = 5

{ х = 7, у = 5

2) { у=х+4, 4х + х+4 + 1 = 0

{ у = х+4, х = -1

{ у = 3, х=-1

3) { у = 4 - 3х, 5х + 4 - 3х - 10 = 0

{ у = 4-3х, х = 3

{ у = -5, х = 3
