Question

a) d – 9 = 5 b) f – 17 = 0 c) 26 + r = 31 d) v – 8 = 12 e) 9 + h = 25 f) 5 – k = 0

Answer 1

a) d – 9 = 5

d= 5+9

d= 14

14-9=5

b) f – 17 = 0

f= 17+0

f=17

17-17=0

c) 26 + r = 31

r=31-26

r=5

26+5=31

d) v – 8 = 12

v= 12+8

v=20

20-8=12

e) 9 + h = 25

h= 25-9

h=16

9+16=25

f) 5 – k = 0

k= 5-0

k=5

5-5=0
