Answer:
-1/3
Step-by-step explanation:
Step 1. Simplify setup.
12/x - 6 = 18/x - 4
Step 2.Subtract 12/x from both sides.
-6 = 6/x - 4
Step 3. Add 4 to both sides.
-2 = 6/x
Step 4. Divide it all by 6 to leave X alone.
-1/3 = x
So X equals to -1/3.
Oh how fun, functions!! You substitute f(-2) into your starting function so it will look like this:
f(x)=2(5x+7)
f(x)=10x+14
f(-2)=10(-2)+14
f(-2)=(-20)+14
f(-2)=(-6)
divide by negative 2 on each side to find f:
f=3
Hope this helped!!
Answer:

Answer:
- 3
Step-by-step explanation:
let n be the number , then
3n + 4 = n - 2 ( subtract n from both sides )
2n + 4 = - 2 ( subtract 4 from both sides )
2n = - 6 ( divide both sides by 2 )
n = - 3
The number is - 3
