1. Solve:
(i) 2x + 5 = 17
(ii) 3y – 2 = 1
(iii) 5p + 4 = 29
(iv) 4a – 3 = – 27
(v) 2z + 3 = – 19
Solution:
(i) 2x + 5 = 17
2x = 17 – 5
2x = 12
x = 12 / 2
We get,
x = 6
Therefore, the value of x = 6
(ii) 3y – 2 = 1
3y = 1 + 2
3y = 3
y = 3 / 3
We get,
y = 1
Therefore, the value of y = 1
(iii) 5p + 4 = 29
5p = 29 – 4
5p = 25
p = 25 / 5
We get,
p = 5
Therefore, the value of p = 5
(iv) 4a – 3 = – 27
4a = – 27 + 3
4a = – 24
a = – 24 / 4
We get,
a = – 6
Therefore, the value of a = – 6
(v) 2z + 3 = – 19
2z = – 19 – 3
2z = – 22
z = – 22 / 2
We get,
z = – 11
Therefore, the value of z = – 11
