Question

what is the value of x in the equation 2x + x =5
-- -
3 6

Answer 1

cross multiply

Answer 2

so what happens is you multiply 6 by (2x+x) and 5 by 3.

and we get:

\[6\times3x=5\times3\]

and from here,

18x = 15

and thus,

x = \[15\div18\]

x = 0.833333

hope this helped! have a nice day :)
