Someone me my grade is on the line i will give 98 points

2x - 3y - 9z = -32

x + 3z = 8

-3x + y - 4z = -8

Add all the equations together.

-3y - 10z = -32

By looking at the first equation, 2x - 3y - 9z = -3y - 10z.

So 2x = -z.

By looking at the second equation, x + 3z = (-0.5z) + 3z = 8.

So 2.5z = 8, and z = 3.2.

This means that x = -1.6.

Let's substitute into our original equations!

-3.2 - 3y - 28.8 = -32

4.8 + y - 12.8 = -8

Therefore, y = 0!

Since these answers do not contradict each other, they are dependent.

The answers are x = -1.6, y = 0, z = 3.2.

The answers are x = -1.6, y = 0, z = 3.2.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
