What is the answer to 19=-3a-5
stepan [7]

Answer:

\fbox{ \huge{ \sf{ a =  - 8}}}

Step-by-step explanation:

\bigstar{ \sf{ \: 19 =  - 3a - 5}}

\tt{Step \: 1 \: } : Swap the sides of the equation

\longmapsto{ \sf{ - 3a - 5 = 19}}

\tt{Step \: 2 \: } : Move 5 to right hand side and change it's sign

\longmapsto{ \sf{ - 3a = 19 + 5}}

\tt{Step \: 3 \: } : Add the numbers : 19 and 5

\longmapsto{ \sf{ - 3a = 24}}

\tt{Step \: 4 \: } : Divide both sides by -3

\longmapsto{ \sf{ \frac{ - 3a}{ - 3}  =  \frac{24}{ - 3}}}

\tt{Step \: 4} : Calculate

\longmapsto{ \sf{a = -  8}}

\sf ∴ \: the \: value \: of \: a \: is \:  - 8.
