Let's solve your equation step-by-step.
5x−7+2−2x=−26
Step 1: Simplify both sides of the equation.
5x−7+2−2x=−26
5x+−7+2+−2x=−26
(5x+−2x)+(−7+2)=−26(Combine Like Terms)
3x+−5=−26
3x−5=−26
Step 2: Add 5 to both sides.
3x−5+5=−26+5
3x=−21
Step 3: Divide both sides by 3.
3x

Answer:
1) f(3) means the temperature after 3 seconds
2) f(3) = 22 + 1.3(3) = 25.9
Temperature after 3 seconds is 25.9°C
3) f(t) = 35 means after t seconds, temperature was 35°C
4) 35 = 22 + 1.3t
1.3t = 13
t = 10 seconds
