Question

Help me this math I suck at

Answer 1

Answer:

x=-1

Step-by-step explanation:

Step 1- Add 9 to both sides of the equation.

New equation:

3x=-12

Step 2- divide by 3 on both sides of the equal sign to get your answer.

x=-1

Answer 2

Answer:

x = 1

Step-by-step explanation:

This is the answer because:

1) If x equals 1, then -3 x 1 equals -3

2) -3 - 9 = -12 (this is the answer because whenever there are two of the same signs, - and -, you have to multiply the signs, so - times - is equal to a +, therefore the equation will change into 3+9 which equals 12. Once you have 12, put the sign that the bigger number has. 9 has a minus sign in front of it which makes the +12 turn into -12)

Hope this helps! :D
