First step, divide 6 from both sides.
t/6=r^2+1
second step, subtract 1 from both sides
t/6 -1=r^2
Now take the square root of each side.
Done!

Answer:
Hamid's normal weight is 80 kg .
Step-by-step explanation:
Let us assume that the normal weight be x .
As given
Hamid has gained weight.
He now weighs 88kg, which is 10% higher than his normal weight.
10% is written in the decimal form
= 0.10
10% increase in the weight = 0.10 × Normal weight.
= 0.10 × x
= 0.10x
Thus
Total weight of Hamid = Normal weight + 10% increase in the weight
88 = x + 0.10x
88 = 1.10x
x = 80 kg
Therefore the Hamid's normal weight is 80 kg .
