PLEASE HELP!! One side of an equilateral triangle increased by 9 is 31 less than 3 times another side. If the sides are measured in inches, what are the measures of the three sides of the triangle?

You do know they all start out the same size, right?

But then what about all the adding and multiplying?

ALWAYS start by naming things. E = The length of all three sides of the equilateral triangle. Now translate... "One side of an equilateral triangle increased by 9" That's E + 9 "is 31 less than 3 times another side." Okay, so E + 9 = 3E - 31 Anything left to translate or can we proceed with the solution?

Why -31? If it's 31 less than 3 times shouldn't it be +31?

3 times is 3E 31 less than 3 times is 3E - 31 You may be trying to put the 31 on the wrong side of the equation. I do not recommend this. I recommend translating EXACTLY what the problem statement says. That's why I called it the "WRONG SIDE" and not just "the other side if that's how you feel like doing it".
