Question

X equal 3 upon 5 (x + 10)

Answer 1

Answer:

Step-by-step explanation:

x= 3/5(x+10)

x= 3/5x+50

5x/\2 + 50x -3 =0

using quadratic formula,

-b+- _/ b/\2 - 4ac                        _/ = root

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

           2a

So,

 -50 +- _/ 2500 + 60

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

                 10

                        -50 + 16_/ 10

1st possibility= ---------------------

                                  10

                          -50 - 16_/ 10

2nd possibility= --------------------

                                10

Answer 2

Answer:

x = 15

Step-by-step explanation:

x = 3/5(x + 10)

x = x + 10

x = 3x/5 + 30/5

x = ( 3x+30)/5

5x = 3x + 30

5x - 3x = 30

2x = 30

x = 30/2

x = 15

hope it helps you :)
