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=22313
78=2313
so (22313)/(2313)
2/1 times (2313)/(2313)
we can cross out the (23*13) and get
2 as the answer
