solve the equation​

Answer 1

Ques-2:(c) 17/4

5 = 2/3(2x-1)

5 = (4x-2)/3

15 = 4x-2

15 + 2 = 4x

17 = 4x

x = 17/4

Ques-3:(c) 20

0.3x +5 = 0.7x -3

5+3 = 0.4x

8 = 0.4x

x = 8/0.4

x = 80/4

x = 20

Ques-4:(B) 13,15,17

let the numbers be x+1 ,x+3,x+5 since they are odd consecutive numbers.

x + 1 +x+3+x+5 = 45

3x+9 = 45

3x = 36

x = 12

The numbers are 12+1 = 13,12+3 = 15,12+5 = 17

13,15,17
