Question

solve the linear eqvations by matrix inversion method 2x -2y = 4 , 3x + 2y = 6​

Answer 1

Answer:

Hope this helps.

Explanation:

2x -2y = 4

Let's solve for x.

2x−2y=4

Step 1: Add 2y to both sides.

2x−2y+2y=4+2y

2x=2y+4

Step 2: Divide both sides by 2.

2x/2=2y+4/2

x=y+2 y=x−2

For the other one:

Let's solve for x.

3x+2y=6

Step 1: Add -2y to both sides.

3x+2y+−2y=6+−2y

3x=−2y+6

Step 2: Divide both sides by 3.

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

y= −3 /2 x+3
