I hope this was helpful.
If you were at 54 on the number line you would have to cross zero and go an extra 13 steps to get to -13.

Answer:
x is mL of 25% acid and y is mL of 50% acid
We set up 2 equations:
A) x + y = 250
B) .25 x + .50y = .35 * 250 which equals
B) .25x + .50y = 87.50 Multiplying A) by -.5
A) -.5x -.5y = -125 adding the equations we get
-.25x = -37.50
x = 150 mL
y = 100 mL
