Hey!

--------------------------------

Solution #1:

x - 12 = 4

x + (-12) = 4

x + (-12) + 12 = 4 + 12

x = 16 ✔

--------------------------------

Solution #2:

x - 1/2 = 4

x + (-1/2) = 4

x + (-1/2) + 1/2 = 4 + 1/2

x = 4 1/2 ✔

--------------------------------

Solution #3:

x - 1.2 = 4

x + (-1.2) = 4

x + (-1.2) + 1.2 = 4 + 1.2

x = 5.2 ✔

--------------------------------

Hope This Helped! Good Luck!

Answer:

Step-by-step explanation:

(x−1)2=4

Take the square root of each side of the equation to set up the solution for x

(x−1)2⋅12=±√4

Remove the perfect root factor x−1

under the radical to solve for x

.

x−1=±√4

Simplify the right side of the equation.
