If you would like to eliminate the z-term, you can do this using the following steps:
x + z = 6 /*(-2)
3x + 2z = 1
_____________
-2x -2z = -12
<span>3x + 2z = 1
</span><span>_____________
</span>-2x + 3x = -12 + 1
x = -11
The correct result would be <span>x + z = 6 /*(-2).</span>
All you have to do is 5.99x4 which equals 23.96
Answer:
5x+x and x+x+4x
Step-by-step explanation:
5x+x is basically 5x+1x which is 6x since x has an "invisible one" in front of it.
x+x+4x is 2x+4x which is 6x
hope this helps. :)
