Answer:

(3 x [tex]x[/tex]) + (3 x 8) = 42

Step-by-step explanation:

3(x+8) = 42

3*x + 3*8 = 42

3x + 24 = 42

3x = 42 -24

3x = 18

x = 18 / 3

x = 6

Hope this helps :)

[tex]3(x+8) = 42\\=> 3\cdot x +3\cdot 8 = 42[/tex]

YES              

[tex]x +8 = 14\\3\cdot x +3\cdot 8 = 42\\3x + 24 =42[/tex]
