8.6+288:(x-3)=50

help me

Answer 1

`8.6+288:(x-3)=50`

`48 + 288:(x-3) =50`

`288:(x-3) = 50 -48 =2`

`x-3 = 288:2 = 144`

`x =144 +3 = 147`

Answer 2

\(8.6+288:\left(x-3\right)=50\\48+288:\left(x-3\right)= 50\\ 288:\left(x-3\right)=50-48\\ 288:\left(x-3\right)=2\\ \left(x-3\right)=288:2\\ \left(x-3\right)=144\\ x=144+3\\ x=147.\)

Answer 3

\(8.6+288:\left(x-3\right)=50\\ \Rightarrow48+288:\left(x-3\right)=50\\ \Rightarrow288:\left(x-3\right)=50-48=2\\ \Rightarrow x-3=288:2=144\\ \Rightarrow x=144+3=147\)

Answer 4

=147

Answer 5

\(8.6+\dfrac{288}{x-3}=50\\ \Leftrightarrow48+\dfrac{288}{x-3}=50\\ \Leftrightarrow\dfrac{288}{x-3}=2\\ \Leftrightarrow x-3=144\\ \Leftrightarrow x=147\)
