Question

Which of the following BEST describes how use of the multiplication property of equality to isolate the variable x below?

–3x = 12

Answer 1

is there a document that goes with this?

Answer 2

to isolate x you would want to do the opposite of multiplication which would be division. so you would have\[\frac{ -3x }{ -3 }=\frac{ 12 }{ -3 }\] you then will cancel out the -3 on the left side and divide by -3 on the right so you will have \[x=-4\]
