Answer:
The answer to your problem is, x = 9/5
Explanation:
Subtract 3 from both sides
5x+3=12
5x + 3 - 3 = 12 - 3
Simplify
5x + 3 - 3 = 12 - 3
= 5x = 9
Divide from both sides of the same factor
5x = 9
5x / 5 = 9 / 5
Cancel all terms that are both numerator and denominator
5x / 5 = 9 /5
x = 9/5
Therefore the answer to your problem is, x = 9/5
