@RandomYserz bye you dismissed im weak right now
OpenStudy (vuriffy):
Hello, @kweenlexis, you may start off by distributing the 4/5 into those values in the (...)
OpenStudy (vuriffy):
4/5 * 2 = 8/5
4/5 * 5 = 20/5 = 4.
OpenStudy (vuriffy):
This action gets rid the of (....)
which allows for it to state:
8/5x + 4 - 4 = 1.
OpenStudy (vuriffy):
The 4s cancel.
8/5x = 1.

the answer gotta be a fraction
OpenStudy (vuriffy):
The answer is a fraction.
OpenStudy (vuriffy):
Do you know what a reciprocal is?
OpenStudy (kweenlexis):
no
OpenStudy (vuriffy):
It's a value which has been flipped, for example 2/1 reciprocal is 1/2.

oh yeah
OpenStudy (vuriffy):
In this case you can do the same to 8/5 x = 1.
8/5(5/8) = 1
40/40 = 1
1 = 1.
OpenStudy (vuriffy):
Which means x = 5/8 for the solution.
OpenStudy (kweenlexis):
all the answer choice are fractions though
OpenStudy (vuriffy):
What are your choices? 5/8 is a fraction. 5 over 8.
