Please help me with this equation, add process too. Thanks
ICE Princess25 [194]

\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}

Let's solve ~ ☂

\qquad \sf  \dashrightarrow \:  - 0.6(m + 1) = 3

\qquad \sf  \dashrightarrow \:  - (m + 1) = 3 \div 0.6

\qquad \sf  \dashrightarrow \:  - (m + 1) = 5

\qquad \sf  \dashrightarrow \:  - m  -  1= 5

\qquad \sf  \dashrightarrow \:  - m = 5 + 1

\qquad \sf  \dashrightarrow \:  - m =  6

\qquad \sf  \dashrightarrow \: m =  - 6

I hope it helps ~
