Answer 2

Answer:

i) 8

ii) 1

iii) 11

iv) 10

v) -18

vi) 0

Step-by-step explanation:

i) 3x- 4y +1

Substituting the value of x= 1 and y= 3 in given equation,

=> 3(1) - 4(3) + 1

=> 3 - 12 + 1

=> -9 + 1

=> 8 Answer

ii) x - y + 3

Substituting the value of x= 1 and y= 3 in given equation,

=> (1) - (3) + 3

=> 1 -3 +3

=> 1 Answer

iii) 2x +3y

Substituting the value of x= 1 and y= 3 in given equation,

=> 2(1) +3(3)

=> 2 + 9

=> 11 Answer

iv) 8x+ 2y -4

Substituting the value of x= 1 and y= 3 in given equation,

=> 8(1) + 2(3) - 4

=> 8 + 6 -4

=> 10 Answer

v) 5x - 7y - 2

Substituting the value of x= 1 and y= 3 in given equation,

=> 5(1) - 7(3) - 2

=> 5 - 21 -2

=> -16 -2

=> -18 Answer

vi) -20x +4y +8

Substituting the value of x= 1 and y= 3 in given equation,

=> -20(1) + 4 (3) +8

=> -20 +12 + 8

=> -8 + 8

=> 0 Answer
