Answer:

c = 2

Explanation:

First expand 3(4-2c):

3×4=12

3×-2c=-6c

Now our equation is :

2c-4 = 12-6c

Add 4 to both sides:

2c-4+4=12-6c+4

Simplify:

2c = -6c+16

Add 6c to both sides:

2c+6c = -6c+16+16

Simplify:

8c=16

Divide both sides by 8:

8c÷8 = 16÷8

c = 2

Answer:

c = 2

Explanation:

2c – 4 = 3(4 – 2c)

Expand brackets:

⇒ 2c – 4 = 12 - 6c

Add 6c to both sides:

⇒ 8c – 4 = 12

Add 4 to both sides:

⇒ 8c = 16

Divide both sides by 8:

⇒ c = 2
