Simplify the expression: 4(x+3)+3(5−x)

x + 27

x +8

2x + 15

19x + 11

4(x + 3) + 3(5 - x)

First multiply each of the brackets by the number on the outside:

4(x + 3) = 4x + 12

3(5 - x) = 15 - 3x

Then add these into the expression:

4x + 12 + 15 - 3x

Collect the like terms (the things that have the same letters):

4x - 3x = 1x (but remember we don’t write the 1, so it’d just be x)

12 + 15 = 27

Therefore:

x + 27

Your answer would be:

A) x + 27
