Answer: Hello mate!

Let's do it step by step

we have the equation 5t - 2r = 25 and we want to solve it for t.

this is equivalent to isolate t on one side of the equation.

the first thing we need to do is add the same number on each side of the equation ( this does not affect the equality)

we can add 2r in both sides:

(5t - 2r) + 2r = 25 + 2r

5t = 25 + 2r

now we need to divide by 5 into both sides of the equation:

(5t)/5 = (25 + 2r)/5

t = (25 + 2r)/5 = 5 + (2/5)r
