Question

Simplify the following algebraic expression:


- 2(x - 1) + 3(6x – 7)

Answer 1

Explanation:

Hey, there!

While simplifying the algebraic expression you must remember: multiply or take LCM first and then add or or subtract like terms then if there is division then you may cut like terms of numerator and denominator.

Here,

`- 2(x - 1) + 3(6x - 7)`

Is given.

Multiply (x,-1) by -2 and (6x,-7) by 3.

`(- 2x + 2) + (18x - 21)`

open brackets.

`= - 2x + 2 + 18x - 21`

Add and subtract like terms.

`= - 2x + 18x + 2 - 21`

`= 16x - 19`

Therefore, the answer is (16x - 19).

Hope it helps.....
