NCERT Solution for Class 8 Maths Chapter – 2 Linear equation in one variable Exercise – 2.1
Q1. Solve the following equations.
- X – 2 = 7
Solution:-
X – 2 = 7
X = 9
- Y + 3 = 10
Solution:-
Y + 3 = 10
Y = 7
- 6 = z + 2
Solution:-
6 = z + 2
Z = 4
- 3/7 + x = 17/7
Solution:-
3/7 + x = 17/7
X = 2
- 6x = 12
Solution:-
X = 12/6
X = 2
- T/5 = 10
Solution:-
T = 10 x 5
T = 50
- 2x/3 = 18
Solution:-
2x = 18 x 3
2x = 54
X = 27
- 6 = y/1.5
Solution:-
1.6 = y/1.5
Y = 1.6 x 1.5
Y = 2.4
- 7x – 9 = 16
Solution:-
7x = 16 + 9
7x = 25
X = 25/7
- 14y – 8 = 13
Solution:-
= 14y = 13 + 8
Y = 3/2
- 17 + 6p = 9
Solution:-
= 6p = 9 – 17
= 6p = -8
= p = -4/6
= p = -4/3
- X/3 + 1 = 7/15
Solution:-
X/3 + 1 = 7/15
X/3 = 7/15 – 1
X/3 = (7 – 15)/15
X/3 = -8/15
X/3 = -8/15 x 3
X/3 = -8/5
