Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations. 3x - 4y - 5z = -27 2x - y + 3z = 9 x - 4y - 2z = 1

the answer to the question is a  

it has the same slope and the same y-intercept.

your answer would be b

step-by-step explanation:

the answer is c. 23/3

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
