equation - x + x + 10 - 8 = 140

answer - 2x + 10 = 140 + 8

2x + 10 = 148

2x = 148 - 10

2x = 138

x = 138/2

x = 69

Checking answer

LHS = x + x + 10 - 8 = 69 + 69 10 -8 = 140

RHS = 140

LHS = RHS

-------> The value of x is 69

answer - 2x + 10 = 140 + 8

2x + 10 = 148

2x = 148 - 10

2x = 138

x = 138/2

x = 69

Checking answer

LHS = x + x + 10 - 8 = 69 + 69 10 -8 = 140

RHS = 140

LHS = RHS

-------> The value of x is 69

answer - If there is no constitution the following may happen :

1) - The representatives may misuse their power

2) - This misuse of power may result in injustice and discrimination

1) - The representatives may misuse their power

2) - This misuse of power may result in injustice and discrimination

answer - Let the common multiples of boys and girls be 7x and 5x

number of girls = 5x

number of boys = 7x + 8

according to condition

7x - 5x = 8

2x = 8

x = 8/2

x = 4

number of boys = 7 X x = 7 X 4 = 28

number of girls = 5 X x = 5 X 4 = 20

-------> number of boys is 28 and number of girls is 20
