Question

f ) x/2=49
g)x/3=1 000
j)2x=1
k) (x+1)+4=9

Answer 1

f) x = 49 .2 = 98

g) x = 3 . 1000 = 3000

j) x = 1/2

k) (x+1) = 9-4
     x+1 = 5
     x = 5-1 = 4

Answer 2

f)

 x = 49
---
 2

x = 2.49
x = 98
---------------------------------
g)

 x  = 1000
--- 
 3

x = 3.1000
x = 3000
----------------------------------------
j)
2x = 1
x = 1/2
------------------------------
k)

x + 1 + 4 = 9
x + 5 = 9
x = 9 - 5
x = 4
