how do i solve x+4(5/7)-8=6

Question

how do i solve

 

Answer 1

x+4(5/7)-8=6 x+20/7-8=6 x=-20/7+14 so now lets take common dinominator which is 7 x= 20+98 x=118/7

Answer 2

x+4(5/7)-8=6

 

now add 8 to both sides to get

 

x+4(5/7)=14

 

Re-write as x+ (20/7) = 14 but 14 = (98/7) so:

 

x+(20/7) = (98/7)

 

Hence: x = 98/7 - 20/7 = 78/7

 Which is the same as x= 11 and 1/7. Let me know if you have other questions. Hope this helps.
