Find the solutions to the following equation: $(x + 1)/(3) - (2x - 1)/(x) = - 1$

Answers

Answer 1

Answer:

Answer:

x=1+/-4i

Step-by-step explanation:

(x+1)/3-(2x-1)/x=-1

find the common denominator,

in this case, it's going to be 3x.

(x^2+x)/3x-(6x-3)/3x=-1

(x^2+x-6x+3)/3x=-1

x^2-5x+3=-3x

x^2-5x-(-3x)+3=0

x^2-5x+3x+3=0

x^2-2x+3=0

apply the quadratic formula in order to find the roots for x.

Since ax^2+bx+c=0, in this case,

a=1, b=-2, c=3

--------------------------

x=(-b+/-sqrt(b^2-4ac))/2a

x=(2+/-sqrt(4-12))/2

x=(2+/-8i)/2

x=1+/-4i

A total of 562 tickets were sold for the school play. They were either adult tickets or students tickets. There were 62 more student tickets sold than adult tick. how many adult tickets were sold ?

Answers

answer: there were 250 adult tickets sold.

explanation: write an equation for this problem.

x + (x + 62) = 562
keep in mind that x is the number of adult tickets, and (x + 62) is the number of student tickets.

now solve.

x + (x + 62) = 562.
2x + 62 = 562
2x = 562
x = 250
