Question

Please help me! How do u do these?

Answer 1

Q3: x = -2

Q6: x = -24

Explanation:

Q3:

`3 - x = 5`

A rule in algebra that you must follow is that whatever you do to the left, you do to the right.

For this question, subtract 3 from both sides to isolate the variable x.

`- x = 5 - 3`

`- x = 2`

Now, divide both sides by -1.

`( - x)/( - 1) = (2)/( - 1)`

`x = - 2`

Q6:

`(x)/(6) = - 4`

Multiply both sides by 6:

`x = - 4 * 6`

`x = - 24`
