‘it costs per person to skate at a roller rink a group pays a total of for i i skating people canceled because they could not go to find how i many people were originally going skating you can set up the equation i = 84, where x is he number of original skaters drag steps of the ‘ solution into order to solve for x.

As it says, set up the equation
7(x - 4) = 84

the parentheses mean you multiply, so it is really
7 × (x - 4) = 84
Now, find how many people are left after the 4 people canceled84 ÷ 7 = 12
There are 12 people
Now, add the 4 people that canceled
12 + 4 = 16

x = 16 people
There was 16 people originally going skating.

yes

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

Suredude why not right
