%28T+%2B+P%29%2FT+=+1.25
T + P = 1.25T ---- Cross.multiplying 
    P = 1.25T - T
    P = .25T

To solve the given equation for T, the objective is to manipulate the given equation to get an equivalent equation in which all the terms with T are on one side of the equation.

%28T%2BP%29%2FT=1.25
T%2BP=1.25T
P=1.25T-T
P=0.25T

Then divide by the coefficient to get T by itself.

P%2F0.25=T or T=P%2F0.25, which is equivalent to T=4P
