do y2-y1 over x2-x1... 8-(-8)/ -2-(-2) and then you simplify it. type that in the calculator i don’t have one on me right now that’s why i didn’t put the answer. hope this helps somehow ..
<span>10x + 30(2) = 20(x + 2) 10x + 60 = 20x + 40 10x = 20 answer x = 2 liters So you would need 2 liters of the 10% solution to make the 30% solution 20%.</span>
