Question

Write the augmented matrix, and use row reduction to solve.
{2y=x+1
3x-2=y

Answer 1

put the equations into a standard form x y constant
-x + 2y = 1
3x - 1y = 2

or, using just the coefficients
-1 2 1
3 -1 2

now use row reduction (make the 3 in the 2nd row zero)

Answer 2

then back solve: start at the bottom and solve for y. use y's value in the top row to find x

Answer 3

Thank you! (:
