Answer:+6
Step-by-step explanation:
2 times 2z= 4z 2 times 4=8 -2 times 3z= -6z -2 times 10= -20 then after u do the multiplication you do this! step by step! 6z minus 4z= 2z then do -20 minus 8= -12 divided by -2z 1 should be= +6
The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45
Answer:
ok so the sale ticket cost 54 so we want to find what the regurler one cost so lets just make a algreva equation
0.9x=54
divide by 0.9
54 divide by 0.9=60
so a regurer ticket cost 60
54=0.9r
Hope This Helps!!!
