Question

(21) If x-1 = 9, Find the value of (1x)2​

Answer 1

Answer:

$x - 1 = 9 \\ {(1x)}^{2} = 100$

Explanation:

$x - 1 = 9 \\ x = 9 + 1 \\ x = 10 \\ {(1x)}^{2} = {(1 \times 10)}^{2} \\ = {10}^{2} \\ = 10 \times 10 \\ = 100$

Answer 2

Answer:

solving (1x)2= 2x

so,

putting the value of

2x-1=9

2x=9+1

2x=10

x=5
