Question

x and y are numbers take from the list below 5,6,7.8.9.10 (i) what values of x and y will make 3x - 2y zero? x = y =

Answer 1

Step-by-step explanation:

3x−2y=0

2x+y=7

y=7−2x

3x−2(7−2x)=0

3x−14+4x=0

7x=14

x=2

3(2)−2y=0

6−2y=0

2y=6

y=3

Answer 2

Step-by-step explanation:

3x - 2y = 0 2x + y = 7 y = 7 - 2x 3x - 2(7 - 2x) = 0 3x - 14 + 4x = 0 7x = 14 x = 2 3(2) - 2y = 0 6 - 2y = 0 2y = 6 y =
