448.80 is the price but let’s not add the sales tax 476.85
You can use the substitution method.
You substitute the first equation to the second equation to get the value of x.
x + 3y = -14
x + 3(2x) = -14
x + 6x = -14
7x = -14
x = -14/7 = -2
Substitute the value of x to the first equation.
y = 2(-2) = 4
