Question

guys this is awakard these questions should be easy but I can't seem to find the equation I would like if you were to help me out​

Answer 1

Step-by-step explanation:

7) Let brother's age be x

Meera's age = x+10

AFTER THREE YEARS :

Meera's age =x+10+3 = x+13

brother's age = x+3

ATQ: ( According To Question)

3(x+13) = 4(x+3)

3x+39 = 4x + 12

x = 27

Meera's present age = x+10

= 27+10

= 37

8) let the three consecutive integers be x , x+1 , x+2

ATQ:

2x + 4(x+1) + 6 (x+2) = 160

12x + 16 = 160

12x = 160 - 16

x = 144 ÷ 12

x = 12

Three integers are : 12 , 13 , 14

The equations are easy you just need some practice.
