Answer: x=-3

Reasoning: 3+5x=-12

First subtract 3 from both sides (3-3 and -12-3)

5x=-15

Now divide both sides by x (5x/5 and -15/5)

x=3

Hey there!

Answer = -3(x = -3)

Step-by-step explanation:

Question:

3 + 5x = -12

Simplify both sides of the equation:

5x + 3 = -12

Subtract three from both sides:

5x + 3 - 3 = -12 - 3

Divide both sides by five:


(5x)/(5)= (-15)/(5)

x = -3

So therefore, that is how you found your answer: x = -3
