Solve each of the equations below and check your answer

Question

A) x + 5 = 8
B) 2 x = 4
C) x / 3 = 2

Answer 1

A)

x + 5 = 8 ------------> (1)

Subtract " 5 " from each side

x + 5 - 5  =  8 - 5

x  =  3

Verification :

Substitute x = 3 in equaion (1)

3 + 5  =  8

8  =  8

Hence Proved.

B)

2 x = 4 --------------> (2)

Devide with " 2 " each side

(2x) / 2  =  4 / 2

x  =  2

Verification :

Substitute x = 2 in equaion (2)

2 X 2  =  4

4  =  4

Hence Proved.

C) 

x / 3 = 2 ------------->(3)

Multiply " 3 " to each side

(x/3) X 3  =  2 X 3

x  =  6

Verification :

Substitute x = 6 in equaion (3)

6 / 3  =  2

2  =  2

Hence Proved.

Answer : 

A) x  =  3 

B)  x  =  2 

C)  x  =  6
