Question

a) x+1=9 b)x-2=8 c) x-8=-10 d) x-2=8 e)x+101=300
f)x-279=300 g)17+x=13 h)128+x=900

Answer 1

a)x+1=9
x = 9 - 1
x = 8

b)x-2=8
x = 8 + 2
x = 10

c)x-8=-10
x = -10 + 8
x = -2

d)x-2=8
x = 8 + 2
x = 10

e)x+101=300
x = 300 - 101
x = 199

f)x-279=300
x = 300 - 279
x = 21

g)17+x=13
17 - 13 = x
x = 4

h)128+x=900
x = 900 - 128
x = 772
