There is no solution.
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
a/5 + 3 = 8 a/5 = 5 a = 25
5 to the second power
x = 25 / 3squared + 5
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5

5.
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
5x = 25Divide both sides by 5:x = 5
a/5 + 3 = 8 a/5 = 5 a = 25
5 to the second power
x = 25 / 3squared + 5
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
To solve 8 to power 25, you either need the mathematical tables or a scientific calculator.
1 over 5^2. which is 1/25
25
Example: n\5 = 5\25...... We will just cross multiply 5 and 5 then the answer will be divided into 25... So 5x5 equals 25 and the other number 25, divide it... 25 divide 25 equals 1 So the answer is 1 n= 1 Hope it helps :)
