Answer:
answer is:

Step-by-step explanation:
we are asked to find which system of equations can we use to find the roots of the equation:

since the system of equation in last part is given as:

so, on equating both the equations i.e. on equating both the values of 'y' we get the desired equation as:
.
Answer:

Answer:60 male staff
Step-by-step explanation:
Ok, there are 96 female staff. The ratio of male to female is 3:4. We’re going to use a proportion which looks like this. 3/4 = x/96. X is a variable that takes the place of the male staff since we don’t know what it is. Now, the question is what do we do to get from 4 to 96. So 96/4 = 24, so 4 x 20 = 96. To keep this ratio equivalent whatever you do to the top you have to do to the bottom so 4 x 20 = 96 and 3 x 20 = 60. So there are 60 male staff.
