Question

4z/11 + 3/11 = -1

Answer 1

4z/11+3/11=-1
Since Denominators are same we can add numerators
4z+3/11=-1
4z+3=-11
4z=-11-3
4z=-14
z=-14/4=-7/2

Answer 2

\(\Large \color{MidnightBlue}{\Rightarrow {4z + 3 \over 11} = -1 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 4z + 3= -11 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 4z = -14 }\)

\(\Large \color{MidnightBlue}{\Rightarrow z = {-14 \over 2} = {-7 \over 2} = -3.5 }\)
