An equation is formed of two equal expressions. Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) Let the amount of time spent on soccer be represented by y, while the amount of time spent on softball is represented by x. Therefore, we can write,
x+y=18
y=2x+1.5
Hence, the system of equations to model the situation is x+y=18 and y=2x+1.5.
B.) Substitute the value of y from the second equation in the first equation, therefore,
x+y=18
x+2x+1.5=18
3x = 16.5
x = 5.5 hours
Substitute the value of x in the second equation, we will get,
y=2x+1.5
y=2(5.5)+1.5
y=11+1.5
y=12.5 hours
Hence, Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.
