2x-3y=13
X+2y=-4
Use linear combination method to solve

x = 2

y = - 3

Step-by-step explanation:

The system of simultaneous linear equations is expressed as

2x-3y=13- - - - - - - - - - - - - -1

x+2y=-4 - - - - - - - - - - - - -- -2

We would eliminate x by multiplying equation 1 by 1 and equation 2 by 2. It becomes

2x - 3y = 13 - - - - - - - - - - - - - 3

2x + 4y = - 8 - - - - - - - - - - - - - 4

Subtracting equation 4 from equation 3, it becomes

- 3y - 4y = 13 - - 8

- 7y = 21

Dividing the left hand side and the right hand side of the equation by

- 7, it becomes

- 7y/- 7 = 21/-7

y = - 3

Substituting y = - 3 into equation 2, it becomes

x + 2 × - 3 = - 4

x - 6 = - 4

Adding 6 to the left hand side and the right hand side of the equation, it becomes

x - 6 + 6 = - 4 + 6

x = 2
