Answer:x=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8+4==2(x-1)

8+4=(2)(x)+(2)(-1)(Distribute)

8+4=2x+-2

(8+4)=2x-2(combine like terms)

12=2x-2

Step 2: flip the equation

2x-2=12

Step 3: Add 2 to both sides.

2x-2+2=12+2

2x=14

Step 4: Divide both sides by 2.

2x/2=14/2

X=7

Hope it helps
