Answer 1

Answer:

The answer for part(a) is 8 and part (b) is 7.

Step-by-step explanation:

From the equation in part (a), y-4=4 , by using trial and error and a bit of mental maths we input y=8 and we get 4=4 which is correct.

From equation in part (b) solving with transposing,

$5t - 25 = 10 \\ 5t = 10 + 25 \\ 5t = 35 \\ t = \frac{35}{5} \\ t = 7$

And there you go! Solved and explained. Please mark as brainliest will be highly appreciated :)
