Answer 2

$\huge\underline\mathfrak\purple{αnswer:}$

1. Let the number be = x

ATQ

5x+7=27

5x=27-7

5x=20

$x = \cancel{\frac{20}{5}}$

$x = 4$

2. Let the number be = x

= 2x+4=18

=2x=18-4

=2x=14

$= x = \cancel{ \frac{14}{2} }$

$x = 7$

3. Let Amit's age Be = x

His father's age = 4x

= 4x-x=27

= 3x=27

$= x = \cancel{ \frac{27}{3} }$

$= x = 9$

4. Let one number be = x

Let the other number be = (72-x)

= x-(72-x) =12

= x-72+x=12

=2x =12+72

= 2x=84

$= x = \cancel{ \frac{84}{2} }$

$= x = 42$

One number = 42

Other number = 72-42 = 30

5. Let the number be = x

= 13x-7x=12

= 6x=12

$= x = \cancel{ \frac{12}{6} }$

$x = 2$

6. Let the number be = x

$= x - \frac{x}{3} = 7$

$= \frac{3x - x}{ 3} = 7$

$\frac{2x}{3} = 7$

$x = 7 \times \frac{3}{2}$

$x = \frac{21}{2}$

$= x = 10.5$

7. Let the number be = x

= 6x-x=10

= 5x=10

$= x = \cancel{ \frac{10}{5} }$

$x = 2$

8. Let the number be = x

= x-1+0.5=7

= x-0.5=7

= x=7+0.5

= x= 7.5
