what is the awnser
7 of one type and 28 of the other
because you may have not specified enough information, i will give the numbers in the ratios. to start, weknow that one is x and one is 4x. add these up to get 5x, and since there are 35 total, x = 7 and there are 7 of one type and 28 of the other.
for this case we have a system of two equations with two unknowns.
to solve, we equate both equations:
we have a quadratic equation of the form:
its roots are given by:
we have two roots:
thus, we look for the values of y, by substituting any of the equations:
