Find the x?

(3/1)(16 - x)/3 = (3/1)4
16 - x = 12
- x = - 4
or
x = 4.

4

16 - x = 12
4 = x

(16-x)=4(3)=12
16-12=x,,,then x=4

12 = 16 - x
-4 = -x
x = 4

16-x=12
16=12+x
4=x

x= 4

Original equation:
(16 - x) / 3 = 4

Multiply both sides by 3:
16 - x = 12

Subtract 16 from both sides:
-x = 12 - 16
-x = -4

Now switch the signs on both sides (same as multiplying by -1):
x = 4

x = 4

16 - x = 4 * 3
16 - x = 12
x = 16 - 12
x = 4

The answer is 4.
