Question

Arrange the steps to solve this system of linear equations in the correct sequence.

x + y = -2

2x – 3y = -9

Tiles

Subtract 3x + 3y = -6 (obtained in step 1) from
2x – 3y = -9 (given) to solve for x.

Substitute the value of x in the first equation
(x + y = -2) to get y = 1.

The solution for the system of equations is (-3, 1).
x = -15

The solution for the system of equations is
(-15, 13).

Add 3x + 3y = -6 (obtained in step 1) to
2x – 3y = -9 (given), and solve for x.
x = -3


Substitute the value of x in the first equation
(x + y = -2) to get y = 13.

Multiply the first equation by 3:
3(x + y) = 3(-2)
3x + 3y = -6.

Answer 1

Multiply the first equation by 3

Add 3x+3y=-6 to 2x-3y=-9 to solve for x

Substitute the value of x in the first equation (x+y=-2) to get y=1

The solution for the system of equations is (-3,1)

Explanation:

Answer 2

Multiply the first equation by 3

Add 3x+3y=-6 to 2x-3y=-9 to solve for x

Substitute the value of x in the first equation (x+y=-2) to get y=1

The solution for the system of equations is (-3,1)
