What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the time at which Liza got to the library be = A
Now , the time at which Liza left the library be = B
The value of B = 11:30 AM
And , the equation will be
The total time spent by Liza at the library = 1 hour and 25 minutes
So , the equation is
The time at which Liza left the library - the time at which Liza got to the library = 1 hour and 25 minutes
Substituting the values in the equation , we get
B - A = 1 hour 25 minutes
11:30 AM - A = 1 hour 25 minutes
Adding A on both sides , we get
11:30 AM = 1 hour 25 minutes + A
Subtracting 1 hour 25 minutes on both sides of the equation , we get
A = 11:30 AM - 1 hour 25 minutes
On simplifying the equation , we get
A = 10:05 AM
Hence , The time at which Liza get to the library was at 10:05 AM
