1st: you would plug in 5 as p. your equation would be 5=-4T+45.

2nd: subtract 45 from both sides so that it cancels out. 5-45=-4T+45-45

3rd: simplify. - 40=-4T

4th: divide by - 4 so that it cancels out. - 40/-4=-4T/-4

4th. simplify. 10=T

you can check your answer by plugging in 10 for T. p=-4x10+45

P would equal 5 so T equals 10
