Question

x+y-88=0
2x+y-71=0
value of y=
​

Answer 1

Answer:

85

Step-by-step explanation:

x+y-88=0. 2x+y-71=0

x+y=88-----1 2x+y=71---------2

subtract equation 1 and 2

x+y-(2x+y)=88-71

x+y-2x-y=9

3x=9

x=3

put value of x in equation 1

x+y=88

3+y=88

y=88-3

y=85

therefore value of y is 85
