Answer:
Step-by-step explanation:
To find the inverse function switch variables out and solve for y
If
y=(x+3)/x swap variables to get
(y+3)/y=x then solve for y
y+3=yx
y-yx+3=0
y-yx=-3
y(1-x)=-3
y=-3/(1-x)
y=3/(x-1)
Answer:
In step 2, he needed to divide both sides of the equation by 5
Step-by-step explanation:
we have
Solve for a------> That means isolate the variable "a"
step 1
Subtract 2b to both sides
step 2
Divide by 5 both sides
