# The equation having 5 as a solution is

(a) 4x + 1 = 2

(b) 3 - x = 8

(c) x - 5 = 3

(d) 3 + x = 8

**Solution:**

Let’s solve each of the equation to find out the correct option.

(a) 4x + 1 = 2

4x = 2 - 1

x = 1/4

(b) 3 - x = 8

x = 3 - 8

x = -5

(c) x - 5 = 3

x = 3 + 5

x = 8

(d) 3 + x = 8

x = 8 - 3

x = 5

Hence out of the four options, the correct option is (d) 3 + x = 8

**✦ Try This:** The equation having 8 as a solution is: (a) 4x + 1 = 3, (b) 3 - x = 2, (c) x - 3 = 5, (d) 5 + x = 8

Let’s solve each of the equation to find out the correct option.

(a) 4x + 1 = 3

4x = 3 - 1

x = 2/4

x = 1/2

(b) 3 - x = 2

x = 3 - 2

x = 1

(c) x - 3 = 5

x = 5 + 3

x = 8

(d) 5 + x = 8

x = 8 - 5

x = 3

Hence out of the four options, the correct option is (c) x - 3 = 5
