Which is the correct coefficient matrix for this system? 3x - 4y = 12 x + 6y = 10

The coefficients of x and y in the first equation are 3 and -4, respectively.

The coefficients of x and y in the second equation are 1 and 6, respectively.

The coefficient matrix lists these coefficients in order on successive rows, so it will be ...

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

answer: 4 (:
