Answer: x = -3/5
Explanation:
In order to find x, we should first write the equation.
The product of 5 and the sum of a number x and 3 is 12.
The sum of x and 3 => x + 3
5 times the sum => 5(x + 3)
this equals 12 => 5(x + 3) = 12
solve for x :
5(x + 3) = 12
5x + 15 = 12
5x = 12 - 15
5x = -3
x = -3/5 {answer}
