[tex]\frac{156}{8x+14}=\ \ \ \ \ | substitute\ x=8\\\\ \frac{156}{64+14}=\frac{156}{78}=2\\\\Solution\ is\ 2.[/tex]
apologiabiology
so first we have to find out what the bottom number is so

8x+14
subsitute 8 for x
8(8)+14
64+14
78

so 156/78
an easy way to do this is to factor it out and find the 'ones' like 4/8=1/2 times 4/4 (4/4=1 and can be canceled out)
*=times
156=2*2*3*13
78=2*3*13

so (2*2*3*13)/(2*3*13)
2/1 times (2*3*13)/(2*3*13)
we can cross out the (2*3*13) and get
2 as the answer
