If all the signs negative it'll be negative because there are 3 number. neg*neg equals positive. positive *neg is neg. pos*pos*pos is positive
Answer:
They subtracted 2x from both sides.
Step-by-step explanation:
They removed 2x from each side because in order to find x it will have to be removed on one side. Since 2x - 2x = 0 it is 2x is out of the equation for the right side and on the left side -2x -(-4x) = -6x which means that there is one x variable left in the equation thus making it solvable.

Jin: 3 small candles and 1 medium candle
3s + 1m = 3.85 <-- equation 1
Trish: 4 small candles and 5 medium candles
4s + 5m = 10.45 <-- equation 2
Solving the system of equations,
s = $0.8/small candle
m = $1.45/medium candle
