Question

pls guys solve this problem​

Answer 1

Answer:

1(d) 7

2(c) Remains the same

3(a) x= 2, y=2/3

4(b) x=1, y=2

5(a) Natural numbers

Answer 2

1...)2x+8y=70..(we have x=7)

2(7)+8y=70

14+8y=70

8y=70-14.

8y=56

y=7....(option D)

2....) depends on equation

3...) option A

3x+3y=8

3(2)+3(2/3)=8

6+2=8

hence proved

4..)option B

3x+y=5

3+2=5

proved

5..)natural no

HOPE THIS WAS HELPFUL
