KSEEB Solutions for Class 8 Maths Chapter 2 Linear Equations in One Variable Ex 2.1

Solve the following equations.

Question 1.
x – 2 = 7
Solution:
We have x – 2 = 7
x – 2 = 7
x = 7 + 2
x = 9
Check: L.H.S = 9 – 2 = 7 = R.H.S

Question 2.
y + 3 = 10
Solution:
y + 3 = 10
y + 3 – 3 = 10 – 3 [Subtracting 3 from both sides]
y = 7
Check: Substituting y = 7 in the given equation
L.H.S = 7 + 3 = 10 = R.H.S

Question 3.
6 = z + 2
Solution:
6 = z + 2
6 – 2 = z + 2 – 2 [Subtracting 2 from bcth sides]
4 = z
z = 4
Check: Substituting the value of z = 4 in R.H.S.
R.H.S = z + 2 = 4 + 2 = 6 = L.H.S
