Question

Three times a number decreased by seven equals for times a number plus eleven

Answer 1

The number is negative eighteen.

Explanation:

First create an equation with the words: ("x" being the number)

3x - 7 = 4x + 11

Now we want put all number on the same side.

3x - 18 = 4x

Now all variables ("x") on the same side.

- 18 = x

Only x is left over and no need to simplify.
