Question

Two sepp equtions with intgefs
9+m/3=2
slove

Answer 1

Answer:
`m=-21`

Step-by-step explanation:

In order to solve the exercise, you need to remember the following properties:

1. Addition property of equality:

If
`a=b`, then
`a+c=b+c`

2. Subtraction property of equality:

If
`a=b`, then
`a-c=b-c`

3. Divison property of equality:

If
`a=b`, then
`(a)/(c)=(b)/(c)`

4. Multiplication property of equality:

If
`a=b`, then
`a*c=b*c`

Then, given the following equation:

`9+(m)/(3)=2`

You need to followw these steps in order solve for "m":

- Apply the Subtraction property of equality subtracting 9 from both sides of the equation:

`9+(m)/(3)-9=2-9\\\\(m)/(3)=-7`

- Apply the Multiplication property of equality multiplying both sides of the equation by 3. Then, you get:

`(3)((m)/(3))=(-7)(3)\\\\m=-21`
