Question

152 - 2 . (x + 1) = 80

Answer 1

\(152-2.\left(x+1\right)=80\)
\(2.\left(x+1\right)=72\)
\(x+1=36\)
\(x=35\)

Answer 2

\(152-2\left(x+1\right)=80\\ 2\left(x+1\right)=152-80\\ 2\left(x+1\right)=72\\ x+1=72:2\\ x+1=36\\ x=36-1\\ x=35\)

Answer 3

\(152 - 2 . (x + 1) = 80\)

\(2.\left(x+1\right)=152-80\)

\(2.\left(x+1\right)=72\)

\(x+1=72:2\)

\(x+1=36\)

\(x=36-1\)

\(x=35\)
