Question

16 + 5x = 8x + 4

need the answer to be a whole number or decimal not a fraction etc.

Answer 1

4

Explanation:

1. First collect the like terms :8x-5x=16-4
2. work them out. 3x=12
3. divide both sides by 3. x=4

Answer 2

x=4

Explanation:

You first add like terms:

16-16+5x=8x+4-16

5x=8x-12

5x-8x=8x-8x-12

-3x=12

Now you divide to isolate the variable:

-3x/-3=-12/-3

Since the denominator and numerator are both negative, the answer will be positive:

x=4

Hope that made sense!
