Answer:
5x-12 > with the _ on the bottom 6+2x
Step-by-step explanation:
x is the number/variable
time taken by a worker= 1/3 hours
time taken by the new worker= 1/5 hours
time taken to complete the work if they work together
= 1/3 + 1/5
= 5+3/15
=8/15
=15/8 hours
You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.
You would solve this equation like so:
6z - 2 = 0 The given equation
6z = 2 Add 2 to both sides
z = 1/3 Divide both sides by 6
Answer:
z = 1/3
Hope this helps.
