Exercise 1.3

Solution

a
To solve the equation, we need to isolate on one side of the equation. Subtracting from both sides will "cancel" it from the right-hand side.
b
To solve the equation we have to isolate on one side. By adding to both sides, we can cancel out and isolate
c
To solve the equation we have to isolate on one side of the equation. By dividing both sides of the equation by we can remove the coefficient on the left-hand side.
d
By multiplying both sides of the equation by we can eliminate the denominator and isolate
