Question

Simplify the following algebraic expression:

2(3x + 4) - 3

a. 6x + 1
b. 6x + 5
c. 6x + 8
d. 6x + 2

Answer 1

Lets use the rainbow method.

First , 2 x 3X = 6X
2 x 4 = 8

Hence , 6X + 8 - 3

6X + 5

Answer 2

b

Explanation:

use BODMAS

first we multiply (3x+4) by 2 then we subtract 3 from the the answer we get from multiplication(we subtract the number not the one with the exponent/3x)
