Solve the system of equations. x + 3y = −1
2x + 2y = 6

(−4, 1)

(2, −1)

(4, −1)

(5, −2)

(5,-2)

Step-by-step explanation:

Multiplying the first equation by 2 we get

2x+6y=-2

Subtracting the second equation we get

4y=-8

y=-2

Plugging y as -2 into the equation we get x=5

(5, -2)

Step-by-step explanation:

x + 3y = −1  

2x + 2y = 6 ⇒ x+y=3

Subtract second equation from the first one:

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.

it is x equals 3   plese mark me really need it
