Question

123 – 5 .( x : 2 + 4 ) = 38

Answer 1

\(123-5\left(x:2+4\right)=38\\ \Rightarrow5\left(x:2+4\right)=85\\ \Rightarrow x:2+4=17\\ \Rightarrow x:2=13\\ \Rightarrow x=26.\)

Answer 2

\(123-5\left(x:2+4\right)=38\)

\(5\left(x:2+4\right)=123-38\)

\(5\left(x:2+4\right)=85\)

\(x:2+4=85:5\)

\(x:2+4=17\)

\(x:2=17-4\)

\(x:2=13\)

\(x=13.2\)

\(x=26\)

Answer 3

\(123-5\left(x:2+4\right)=38\\ 5\left(x:2+4\right)=85\\ x:2+4=17\\ x:2=13\\ x=26\)
