Which of the following equations cannot be formed using the equation x = 7 (a) 2x + 1 = 15 (b) 7x - 1 = 50 (c) x - 3 = 4 (d) x/7 - 1 = 0

Solution:

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

(a) 2x + 1 = 15

2x = 15 - 1

x = 14/2

x = 7

(b) 7x - 1 = 50

7x = 50 + 1

x = 51/7

(c) x - 3 = 4

x = 4 + 3

x = 7

(d) x/7 - 1 = 0

x/7 = 1

x = 7

Hence out of the four options, the correct option is (b) 7x - 1 = 50

✦ Try This: Which of the following equations cannot be formed using the equation x = 2 ? (a) 2x + 1 = 5, (b) 7x - 1 = 13, (c) x - 3 = 1, (d) x - 1 = 1

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

(a) 2x + 1 = 5

2x = 5 - 1

x = 4/2

x = 2

(b) 7x - 1 = 13

7x = 13 + 1

x = 14/7

x = 2

(c) x - 3 = 1

x = 1 + 3

x = 4

(d) x - 1 = 1

x = 1 + 1

x = 2

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