Answer:
-40
Step-by-step explanation:
13-2x = 93
-2x = 93-13
-2x = 80
x = -40
15, because:
1x1=1
1x2=2
2/1=2
2+13=15
Factor in "x" the expression:
25/100
27/108
31/124
these three equal 1/4 or 1:4
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>
