Pick 2 and show work

olga2289 [7]

3x+2y-4z=12 add 4z on both sides
3x+2y=12+4z subtract 2y on both sides
3x=12+4z-2y divide 3 on both sides
x= 4+4/3z-2/3y
x= 4+1.25z-.67y

3x+2y-4z=12 subtract 3x on both sides
2y-4z=12-3x add 4z to both sides
2y=12-3x+4z divide 2 on both sides
y=6-3/2x+4/2z
y=6- 1.5x+2z

3x+2y-4z=12 subtract 3x on both sides
2y-4z=12-3x subtract 2y on both sides
-4z=12-3x-2y divide by -4 on both sides
z=-3-3/4x-2/4y
z=-3-.75x-.5y

your welcome you can do the other one

How many solutions does this

weeeeeb [17]

<h3>Answer:</h3>

<h3>Step-by-step explanation:</h3>

Given equation:

$3s = 8s - 5s$

To simplify this equation, we need to isolate the variables on one side of the equation and the constants on the other side of the equation. To do this, we can <u>simplify the R.H.S</u> as like terms can subtract.

⇒ $3s = 8s - 5s$

⇒ $3s = s(8 - 5)$

⇒ $3s = s(3) = 3s$

⇒ $3s= 3s$

Since both sides of the equation are the same, this system of equations has infinite solutions.

<h3 /><h3>Check:</h3>

We can check our answer by substituting the value of "s" into the equation. As a result, you will see that many values of "s" are satisfying the equation. Thus, Option D is correct.
