3. Solve:
(i) – 8m – 2 = – 10
(ii) 4x + 2x = 3 + 5
(iii) 4x – x + 5 = 8
(iv) 6x + 2 = 2x + 10
(v) 18 – (2a – 12) = 8a
Solution:
(i) – 8m – 2 = – 10
– 8m = – 10 + 2
– 8m = – 8
m = – 8 / – 8
We get,
m = 1
Therefore, the value of m = 1
(ii) 4x + 2x = 3 + 5
6x = 8
x = 8 / 6
We get,
x = 4 / 3
x =
Therefore, the value of x =
(iii) 4x – x + 5 = 8
3x = 8 – 5
3x = 3
x = 3 / 3
We get,
x = 1
Therefore, the value of x = 1
(iv) 6x + 2 = 2x + 10
6x – 2x = 10 – 2
On further calculation, we get
4x = 8
x = 8 /4
x = 2
Therefore, the value of x = 2
(v) 18 – (2a – 12) = 8a
18 – 2a + 12 = 8a
30 = 8a + 2a
30 = 10a
a = 30 / 10
We get,
a = 3
Therefore, the value of a = 3
