Answer:

a=80,b=100,c=40 & d=120

Step-by-step explanation:

a+b+c=220

putting value of b+c

a+140=220

a=220-140

a=80

a+d=200

putting value of a

80+d=200

d=200-80

d=120

d+c=160

putting value of d

120+c=160

c=160-120

c=40

b+c=140

putting value of c

b+40=140

b=140-40

b=100

a + b + c = 220

a + 140 = 220

a = 220 - 140

a = 80

a + d = 200

80 + d = 200

d = 200 - 80

d = 120

d + c = 160

120 + c = 160

c = 160 + 120

c = 40

again ,

a + b + c = 220

80 + b + 40 = 220

120 + b = 220

b = 220 - 120

b = 100
