Answer:
Step-by-step explanation:
Step-by-step explanation:
x - y + 5z = 29
y + 2z = 4
z = 7
since z = 7 we can use this value in second equation
y + 2×7 = 4 and y = -10
now we know the value of y we can solve the first equation
x -(-10) + 5×7 = 29
x + 10 + 35 = 29
x = -11
Six now have a good day happy face bye-bye
17+4=21
21 divided by 3= 7
17 dollars for tickets
21-4=17
so your answer is 21 he has to sweep the floor 21 times to get tickets
