Question

How to solve simultaneous linear equations :
3x+2y=6
6x-y=-8

Answer 1

Explanation:

1). 3x + 2y = 6

__________

* 3x+2y=6

x+2y= -6/ (-1)

We times the second equation by -1 in order to get 2y and -2y.

3x+2y=6

-x-2y= 6

Then we add two equations together:

3x+2y-x-2y=6+6

3x-x=12

2x=12/:2

x=6

Then we put x in the second equation to calculate y:

6+2y= -6

2y= -6-6

2y= -12/:2

y= -6

You can check if the answer is correct or not by putting values of both x and y into both equations.

Hope this helps you❤️
