(3x + 11) for x = 2
Evaluate the expression

17

Step-by-step explanation:

so if x is two it would change the equation to (3*2+11)

since the parenthesis cover the whole equation we can remove those

3*2+11

we would do 3*2 first cause of PEMDAS

that would equal 6 so then we add 11

6+11=17

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
