Question

Evaluate the expression when m=-3
m + 7m+1

Answer 1

m+7m+1 = -23

Step-by-step Step-by-step explanation:

To solve the given equation we will follow the PEDMAS rule.

PEDMAS stands for :

• 
  `\purple\star` P = Parentheses
• 
  `\purple\star` E = Exponents
• 
  `\purple\star` M = Multiplication
• 
  `\purple\star` D = Division
• 
  `\purple\star` A = Addition
• 
  `\purple\star` S = Subtraction
• To solve the given equation we will follow the PEDMAS rule.

Substituting the value of m = 3 to evaluate the expression :

`\begin{gathered} \qquad{\twoheadrightarrow{\sf{m + 7m + 1}}}\\\\\qquad{\twoheadrightarrow{\sf{( - 3) + (7 * - 3) + 1}}}\\\\\qquad{\twoheadrightarrow{\sf{ - 3 - 21+ 1}}}\\\\\qquad{\twoheadrightarrow{\sf{ - 24+ 1}}}\\\\\qquad{\twoheadrightarrow{\sf{ - 23}}} \\\\\qquad{\star{\underline{\boxed{\sf{\red{ - 23}}}}}}\end{gathered}`

Hence, the answer is -23.

Answer 2

__________________________________________________________
In this question, you are solving the expression by plugging in the value "-3" to all of the "m" variables in the expression.

Solve:

Expression: m + 7m + 1

Plug "-3" into the "m" variables and solve.

-3 + 7(-3) + 1
-3 - 21 + 1

-24 + 1

-23

Your final answer should be: -23
