The value of x for which the expressions 3x - 4 and 2x + 1 become equal is
(a) -3
(b) 0
(c) 5
(d) 1

Solution:

Given, the expressions are 3x - 4 and 2x + 1

We have to find the value of x.

According to the question,

3x - 4 = 2x + 1

On grouping of common terms,

3x - 2x = 1 + 4

(3 - 2)x = 5

x = 5

Therefore, the value of x is 5.
