How to Solve an Energy Change Equation Involving Temperature?

[mopar969]

Can you please show me the steps on how to solve this equation for change in energy I have tried but I don't get the answer in the back of the book. I am looking for T

7098+(0.02*4186)(T-0)=(0.1)(910)(25-T)+(0.2*4186)(25-T)
