1. Write a matrix to represent the system.
2a - 3b = 6
a + b = 2
O [2 -3 6]
[ 1 1 2]
O [2 1 -3]
[1 6 2]
O [a b 6]
[a b 2]
O [2a -3b 6]
[a b 2]

2. Write the system of equations represented by the matrix.
[0 1 2 4]
[-2 3 6 9]
[1 0 1 3]
O x + 2y = 4
-2x - 3y + 69 = 0
x + y = 3
O x + 2y = 4
-2x - 3y + 6 = 9
x + y = 3
O y + 2z = 4
-2x + 3y + 6z = 9
x + z = 3
O x + 2z = 4
-2x - 3y + 6 = 9
x + y = 3

Please help, I'm so confused. Xd Brainliest to whoever is correct!
