When solving systems of we have at least two unknowns. A common example of a system of equations is a mixture problem. If I know that the solution I use to clean my car windows is 65% water and 35% cleaner, I have one relationship. If I also know that I only have a 3-liter spray bottle that gives me a second relationship.
Finally, solve the system of equations

Let x be the number of liters of water and y be the number of liters of cleaner.
Then the first equation is
$x+y=t$
where t is total number of liters
Also given that $t=3$.
These are 2 equations that need to be solved simultaneously.
Replace t in the first equation with $t=3$ from the second equation
$x+y=3$
It is given that $x=0.65t$ and $y=0.35t.$
Replace t with 3 and the equations becomes
$x=0.65×3$and $y=0.35×3$
solve for x and y to get $x=1.95$ and $y=1.05$
The amount of water in the 3 liter spray bottle is 1.95 liters.
The amount of cleaner in the 3 liter spray bottle is 1.05 liters.
