Question

Simplify2x - 3+ 7x-9

Answer 1

To simplify this expression, we can start to sum the like terms:

`2x+7x-3-9=9x-12`

We can also notice that both values have the 3 as a common factor, then:

`9x-12=3\cdot(3x-4)`

Therefore, the expression 2x -3 + 7x - 9 is equivalent to 9x - 12 = 3*(3x - 4).

We can use the two results as a simplification of the latter expression.
