Solve the system using substitution x=3y-11 4x-3y=-26
iragen [17]

Answer:

x=3y-11

then now putting the value of x in second equation

4(3y-11)-3y =26

12y - 44-3y=26

9y=44+26

9y=70

y=70/9

now putting the value of  y in 1st equation then

x=3*70/9-11

x=37/3

now checking this is correct or not in 2nd eqn

4*37/3-3*70/9=26

148-70/3=26

26=26

Which classification describes the following syastem of equations? x=5 y=6 -x - y +z = 0
Papessa [141]

Answer:

Is a consistent independent system

Step-by-step explanation:

we know that

If a system has at least one solution, it is said to be consistent .  

If a consistent system has exactly one solution, it is independent .  

If a consistent system has an infinite number of solutions, it is dependent

If a system not have solution, it is said to be inconsistent

we have

x=5 ----> equation A

y=6 ----> equation B

-x-y+z=0 ----> equation C

substitute equation A and equation B in equation C

-5-6+z=0

Solve for z

z=11

The solution is the point (5,6,11)

The system has only one solution

therefore

Is a consistent independent system
