Answer:
X=56
You have to multiply 8 and 7
First you set f(x) and h(x) equal to each other. So 1/x+1=2x+3. Next, you multiply each side by 1 to cancel out the fraction. So now the answer is x+1=2x+3. Now subtract 1 from each side. X=2x+2. Subtract 2x from each side now. -2x=2. Divide by -2x and get the answer x= -1
