During a science lab experiment, Bailey was instructed to mix two solutions together. Before mixing solution A and solution B, she was to measure and record their temperatures. She measured and recorded the temperature for solution A as 12° C. She then mixed the two solutions and measured the new temperature at 0°C. Bailey then realized she forgot to measure the temperature of solution B before she mixed it with solution A. What was the temperature of solution B before the solutions were mixed together?

Temperature of solution A = 12°C

Let the temperature of solution B , be x as we dont know it's actual temperature .

Temperature of new solution = 0°C

The above statements can be written in an equation as :-

Let us check whether or not we have found out the correct temperature of Solution B by placing -12 in the place of x :-

As the left hand side of the equation is equivalent to the right hand side of the equation, we can conclude that we have found out the correct temperature of solution B .

Therefore , the temperature of Solution B = (-12)°C .
