Can someone help me? I don’t understand how to do this.

x=8

Step-by-step explanation:

try

x = 32.5

Step-by-step explanation:

12 + 2x −1 = 4

2x −1 +  12 = 4

Step 1: Add -12 to both sides.

2x − 1 + 12 + −12 = 4 + −12

2x −1 = −8

Step 2: Solve Square Root.

2x − 1 = −8

2x − 1 = (−8)^2     (Square both sides)

2x − 1 = 64

2x − 1 + 1 = 64+1   (Add 1 to both sides)

2x=65

2x/2 = 65/2        (Divide both sides by 2)

x = 65/2

x = 32.5
