Answer:
n=-37
Step-by-step explanation:
9+n/4 = -7
First, we multiply each side by 4:
9+n= -28
Subtract 9 from both sides
n= -37
Hope this helps!!!
2x=16-2y
x=8-y
6(8-y)+4y=38
48-6y+4y=38
48-2y=38
-2y=-10
y=5
8-5=x
x=3 <-Answer
So,

Multiply both sides by 11.

Divide both sides by 7.
f = 1
Check.


This checks.
S = {1}
x = -38/9 !!!
27(x+4)=−6
Step 1: Simplify both sides of the equation.
27(x+4)=−6
(27)(x)+(27)(4)=−6 (Distribute)
27x+108=−6
Step 2: Subtract 108 from both sides.
27x+108−108=−6−108
27x=−114
Step 3: Divide both sides by 27.
27x/27=−114/27
x=−389
