Will give, Branliest.Thanks, :)​

Answer 1

Answer:

X= -9

Y=7

Z=119

X=-70

Y=0.8

z=4.667

Step-by-step explanation:

X=-18-6= -24/3= -9

Y=24+11/5= 35/5= 7

Z=10+7=17*7=119

X=-2-5=-7*10=-70

Y=19-7=12/15=0.8

Z=-2+4=2*7=14/3=4.667

Answer 2

Answer:

-8; 7; 119; 30; 4/5 (0.8); 14/3 (4.6666...)(4 2/3)

Step-by-step explanation:

> 3x + 6 = -18 > 5y - 11 = 24

3x = -18 - 6 5y = 24 + 11

3x = -24 5y = 35

x = -8 y = 7

> z/7 - 7 = 10 > x/10 + 5 = -2

z/7 = 10 + 7 x/10 = -2 + 5

z/7 = 17 x/10 = 3

z/7 = 17 x = 30

z = 119

> 15y + 7 = 19 > 3z/7 - 4 = -2

15y = 19 - 7 3z/7 = -2 +4

15y = 12 3z/7 = 2

y = 4/5 (0.8) z = 14/3 (4.6666...) ( 4 2/3)
