Start by distributing the 3 across the parenthesis. So you have: $$(-3 \times x) + (-3 \times 5) = (-5 \times -3) + (-5 \times -4x)$$

Do the same with both sides. Which is what I did there.

whats the answer

abb0t · Answer

That's where we're going with this. Did you distribute? After you distribute, you have -3x+15 = 15+20x
Your next step is to use your algebra rules to massage this a bit. So basically, subtract 15 from both sides, and you get -3x = 20x
Now, notice how you can divide both sides to get a constant value w/ no x = term? So what do you think the answer might be?
