Write the augmented matrix for the system of linear equations. (Do not perform any row operations.) {x − y + 3z = 3
{9x − 4y + z = −1
{3x + y = 0

Step-by-step explanation:

Write the system of equations as an augmented matrix. Then solve for x and y.

3x+y=-11

-9x-3y=33

a) 32pie square meters

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
