Answer:
x=3, z=-1, y=6
Step-by-step explanation:
you need to make the coefficients of each variable equal to each other then subtract 2 equations.
this one: multiply -4 in 1st
4x+4y+4z=32
-4x+4y+5z=7
_____________
8x+0-z=25
we have 2 equations with 2 variables now
2x+2z=4
8x-z=25
Answer:
5y·2x=21
<em>
</em>
Step-by-step explanation:
using the formula above,you will find the equation 5y–2x=21
D, he is moving at a constant spees
It all the way across a circle so
7.3+7.3=14.6 so that your answer
