Question

Simplify 3 - (4x - 5) + 6.
A) 12x + 21
B) 4x + 14
C) 4x + 4
D) -4x + 14

Answer 1

D) -4x+14

Explanation:

We are given with the expression

3 - (4x - 5) + 6

Here we are going to open the bracket at first step

as we have a negative sign in front of bracket the signs of the terms inside brackets will be reversed

3-4x+5+6

now we bring the like terms together

3+5+6 - 4x

Here 3, 5, 6 all are constant and hence like

14-4x

or

3 - (4x - 5) + 6= -4x+14

Hence our answer is -4x+14
