Answer:

let the number of door tickets be x

so, eventually the number of advanced tickets will be. x-30

the total cost=2630.

(x-30)3+5x=2630

3x-90+5x=2630

8x-90=2630

8x=2630+90

8x/8=2720/8

x=340

x-30

340-30

310.

total tickets sold=310+340=650

Therefore, the total tickets bought was 650, 310 was advanced and 340 was door tickets

7x + 6(-3 + 4x) = 199<br>what does x equal?
tresset_1 [31]

Simplify. Note the equal sign. What you do to one side, you do to the other. Follow PEMDAS.

Isolate the x.

First, distribute 6 to all terms within the parenthesis

6(-3) = -18

6(4x) = 24x

7x - 18 + 24x = 199

Simplify. Combine like terms

31x - 18 = 199

Isolate the x. Add 18 to both sides

31x - 18 (+18) = 199 (+18)

31x = 199 + 18

31x = 217

Isolate the x. Divide 31 from both sides

31x/31 = 217/31

x = 217/31

x = 7

7 is your answer for x

hope this helps
