Simplify 18 - 2[ x + (x - 5) ]. 8 - 4 x 28 - 4 x 28 - 2 x

First u have to factor the expression

2 (9 - (x + (x-5)) x 8 - 2 x 28 - 2 x 28 - x)

next you have to remove the parenthesis and multiply

2 (9 - (x + x - 5) x 8 - 2 x 28 - 2 x 28 - x) that's - 2 x 28

2 (9 - (x + x - 5) x 8 - 56 - 2 x 28 - x)

2 (9 - (x + x - 5) x 8 - 56 - 56 - x)

Check like terms

2 (9 - (2x-5) x 8 - 56 - 56 - x)

multiply by 8

2 (9 - (16x - 40) - 56 - 56 - x)

remove parenthesis

2 (9 - 16x + 40 - 56 - 56 - x)

calculate and collect like terms

2 (-63 - 16x - x)

collect the like terms

2 (-63 - 17x)

your answer is: 2 (-63 - 17x)

The answer for this question is 28-4x
