Question

2 divided by x+2 plus 1 divided by 5 is equal to 6 divided by x +5....... find x :)

Answer 1

a.) x=0
b.)x= -13
c.) x=13
d.) x=0, x=13

Answer 2

-50/29

Answer 3

The answer is (d) x=0, x=13

Answer 4

oops
didnt see the +5

Answer 5

Here is how I calculated the answer to be (d):

2/(x+2) + 1/5 = 6/(x+5) Multiply each term by (x+2) to eliminate the denominator

2 + (x+2)/5 = (6)(x+2)/(x+5) Multiply each term by (x+5) for the same reason

2(x+5) + (x+2)(x+5)/5 = 6(x+2) Multiply each term by 5

10(x+5) + (x+2)(x+5) = 30(x+2)

10x + 50 + x^2 + 7x + 10 = 30x + 60

x^2 +17x +60 = 30x + 60

x^2 + 17x - 30x = 60 - 60

x^2 - 13x = 0

x(x-13) = 0

x = 0 This is one of the solutions

x-13 = 0

x = 13 This is the other solution

Therefore, x=0 and x=13 which is the (d) choice
