Answer:
x = 3
Explanation:
check:
4(x + 2) = 20
4(3 + 2) = 20
4(5) = 20
20 = 20
Hence proved x = 3
c) 2x+1
Step-by-step explanation:
Let's x be number of Nick's goals.
Emma has scored 1 more than twice the number of Nicks.
1 more is +1, of twices the number is 2x.
so 2x+1=15
I think B is the correct choice.
So basically you add x with 9 and you get 9x
3 x (14-3) = 33
