Question

a) 10 = x + 8
b) 15 = x + 20
c) 4 = x - 10
d) 7 = x + 8
e) 0 = x + 12
f) - 0 = x + 10​

Answer 1

a) 10 = x + 8

10 - 8 = x

x = 2

b) 15 = x + 20

15 - 20 = x

x = - 5

c) 4 = x - 10

4 + 10 = x

x = 14

d) 7 = x + 8

7 - 8 = x

x = - 1

e) 0 = x + 12

0 - 12 = x

x = - 12

f) - 0 = x + 10

- 0 - 10 = x

x = - 10
