Step-by-step explanation:
[tex]3(4x + 5) = 33 \\ \\ \therefore \: 12x + 15 = 33 \\ \\ \therefore \: 12x = 33 - 15 \\ \\ \therefore \: 12x = 18 \\ \\ \therefore \:x = \frac{18}{12} \\ \\ \huge \red{ \boxed { \bold{ \therefore \:x = 1.5}}}[/tex]
Answer:
3(4x+5)=33
open the brackets(multiply both by 3)
12x+15=33
Minus 15
12x=18
x=1.5 (18/12)
