N = -5/9
Decimal from is N = -0.555
Answer:
-3
Step-by-step explanation:
First let's solve for u...
-3u+9=6
Subtract 9 from both sides...
-3u=-3
Divide both sides by -3
u=1
Now we plug 1 in for u in the expression 4u-7 to get...
4u-7=4(1)-7=4-7=-3
11.9 would be the correct answer I believe
The simplified equation is -4x + 15y - 27
