Question

a. (35-12-m)=10
b. (38-n-8)=10
c. (b-21-30)=20
d. (i+36-45)=14
e. (78-39+l)=56
​

Answer 1

a.

( 35 - 12 - m ) = 10

23 - m = 10

m = 23 - 10

m = 13

b.

( 38 - n - 8 ) = 10

38 - n = 10 + 8

38 - n = 18

n = 38 - 18

n = 20

c.

( b - 21 - 30 ) = 20

b - 21 = 20 + 30

b - 21 = 50

b = 50 + 21

b = 71

d.

( i + 36 - 45 ) = 14

i + 36 = 14 + 45

i + 36 = 59

i = 59 - 36

i = 23

e.

( 78 - 39 + l ) = 56

39 + l = 56

l = 56 - 39

l = 17
