If x/2 = 3, then the value of 3x + 2 is
(a) 20
(b) 11
(c) 13/2
(d) 8

Solution:

Let’s solve x/2 = 3

x = 2(3)

x = 6

Now put x = 6, in the expression 3x + 2

3(6) + 2 = 20

Hence out of the four options, the correct option is (a) 20

✦ Try This: If x/3 = 2, then the value of 2x + 3 is (a) 6, (b) 5, (c) 15, (d) 7

Let’s solve x/3 = 2

x = 3(2)

x = 6

Now put x = 6, in the expression 2x + 3

2(6) + 3 = 15

Hence out of the four options, the correct option is (c) 15
