Given the following system of equations, type the target variable matrix for x.

Question

5x −  y = 6

2x + 7y = 9

Answer 1

x=51/37

y=33/37

I use the inverse matrix (denominator =37=matrix determinant)

times the vector (6,9)

the inverse matrix is top row 7 and 1,,,bottom row -2 and 5

with denominator of 37
