Bill sold 75 tickets for a naked season gig. he sold x £5 tickets and y £8 tickets. he collected £444. how many of each type of ticket did he sell?

 £5 = 52 tickets,  £8 = 23 tickets

Step-by-step explanation:

                      Quantity        Cost

£5 Tickets           x                 5x

£8 Tickets         y                8y    

    TOTAL          75               444

  Cost:     5x + 8y = 444   →  1(5x + 8y = 444)   →    5x + 8y = 444

Quantity:    x +   y =   75   → -5( x +   y =   75)    →   -5x - 5y = -375

                                                                                         3y =  69

                                                                                           y = 23

Input y = 23 into one of the original equations to solve for x:

x +  y  = 75

x + 23 = 75

x         = 52

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
