1/2 + 3/x = 3/4
multiply everything by x
1/2x + 3 = 3/4x...subtract 1/2x from both sides
3 = 3/4x - 1/2x
3 = 3/4x - 2/4x
3 = 1/4x...multiply both sides by 4
4 * 3 = x
12 = x

Answer:
When n=3 and x=−2 the answer is 11.
Step-by-step explanation:
Given:
Let p (n,x) be the function such that

To Find:
p (n,x) = p ( 3, -2) = ?
Solution:

Substituting n = 3 and x = -2 we get

Negative square gives positive number therefore (-2)²=4


When n=3 and x=−2 the answer is 11.
Answer:
f(7) = -23
Step-by-step explanation:
f(x) = -3x - 2
f(7) = -3(7) - 2
f(7) = -21 - 2 = -23
<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
