Answer:
Step-by-step explanation:
1 > x + 5 = 13 x = 8
2 > (6y-7)/(3y+9) = 1/3
3(6y-7) = 1(3y+9)
18y-21 = 3y+9
18y-3y = 9+21
15y = 30 y = 2
3 > (z-9)/(5+z) = -5/9
9(z-9) = -5(5+z)
9z-81 = -25-5z
9z+5z = 81-25
14z = 56 z = 4
4 > p+3p/10 = 13/10
10p+3p = 13
13p = 13 p = 1
5 > 4q+16 = 5q+10
q = 6
6 > 3(r+10) +200 = 236
3r+30+200 = 236
3r = 236-230
r = 6/3 r = 2
9 X Y Z P 1 Q 2 R 3 = 9824116223
