Use the graph method to solve the system of linear equations: 2x + y = 3 and x + y = 3
A) (-1.5, 0)
B) (0, -1.5)
C) (0,3)
D) (3,0)

Step-by-step explanation:

Graph each line on the same plane and take the point of their intersection.

Given linear equations:

See the attached  to confirm the answer is the point (0, 3)

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
