I want answer with full explanation for class 6​

Answer 1

Answer:

a) 32

b) 2

Step-by-step explanation:

a) 8x + 4y.

[By putting the value of x = 2 and y = 4 then]

= 8×2 + 4×4

= 16 + 16

= 32 (Ans)

b) 3x + y-z

[By putting the value of x = 1, y=2 and z = 3 then]

= 3×1 + 2 - 3

= 3 +2 - 3

= 5 - 3

= 2 (Ans)

Answer 2

Answer:

a) 8x +4y

=8×2+4×4

=16+16

=32

b)3x + y-z

3×1+2-3

=3+2-3

=3-1

=2

Step-by-step explanation:

becaue you can put the value in that X or y or z and get the answer
