Question

Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42

Answer 1

x = 25

Explanation:

(x-7)2 = 36

divide both sides by 2

x-7 = 18

add 7 to both sides

x = 25

Answer 2

`\sf \: x = 25`

Explanation:

Given equation,

→ (x - 7)2 = 36

Now the value of x will be,

→ 2(x - 7) = 36

→ (2 × x) - (2 × 7) = 36

→ 2x - 14 = 36

→ 2x = 36 + 14

→ 2x = 50

→ x = 50/2

→ [ x = 25 ]

Hence, the value of x is 25.
