The equation having - 3 as a solution is
(a) x + 3 = 1
(b) 8 + 2x = 3
(c) 10 + 3x = 1
(d) 2x + 1 = 3

Solution:

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

(a) x + 3 = 1

x = 1 - 3

x = - 2

(b) 8 + 2x = 3

2x = 3 - 8

x = - 5/2

(c) 10 + 3x = 1

3x = 1 - 10

x = - 9/3

x = - 3

(d) 2x + 1 = 3

2x = 3 - 1

x = 2/2

x = 1

Hence out of the four options, the correct option is (c) 10 + 3x = 1

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

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

(a) x + 3 = 4

x = 4 - 3

x = 1

(b) 8 + x = 3

x = 3 - 8

x = - 5

(c) 4 + 3x = 2

3x = 2 - 4

x = - 2/3

(d) 2x - 1 = - 3

2x = - 3 + 1

x = - 2/2

x = - 1

Hence out of the four options, the correct option is (d) 2x - 1 = - 3
