Answer 1

ANSWER

3x−5y+1=0      

x−y+1=0⇒y=x+1

Substitute y=x+1 in 3x−5y+1=0 we get

3x−5(x+1)+1=0

3x−5(x+1)+1=0

⇒3x−5x−5+1=0

⇒−2x−4=0

⇒−2x=4

⇒x=−2

∴x=−2

Substitute x=−2 in x−y+1=0 we get

−2−y+1=0

⇒−y−1=0

∴y=−1

Hence x=−2,y=−1

Answer 2

Answer:

9

Step-by-step explanation:

x+y=14_ _1st x-y=4_ _2nd adding 1st and 2nd x+y+x-y 2x=18 x=18/2=9
