Question

An equation is shown below3m+8+m=36Which of the following values can be substituted for m to make the equations true

Answer 1

`3m+8+m=36`

To find the value of m that makes the equations true you ned to solve for m, as follow:

1. Add similar terms (similar terms are those with the same variable inthis case m) (3m+m=4m)

`4m+8=36`

2. Substract 8 in both sides of the equation:

`\begin{gathered} 4m+8-8=36-8 \\ 4m=28 \end{gathered}`

3. Divide both sides of the equation into 4:

`\begin{gathered} (4m)/(4)=(28)/(4) \\ \\ m=7 \end{gathered}`

4. Prove the solution you get m=7 in the equation.
