Question

solve graphically 2x-y=6,x+y=3​

Answer 1

Answer:

A) 3

Step-by-step explanation:

2x-y=6, 2(x-y)=6,2xy=6,xy=6/2=3

Answer 2

Answer:

2x - y = 6 (1) ,x + y = 3 (2)

x + y = 3

x = 3 - y

put the value x in equation (1)

2x - y = 6

2(3 - y) - y = 6

6 - 2y - y = 6

- 3y = 0

y = 0

put the value y in equation (2)

x + y = 3

x + 0 = 3

x = 3
