Answer:
Step-by-step explanation:
f(x) = x is an odd function; the power of x is x^1.
f(x) = -x is also an odd function.
When solving system equations, we can use substitution method or elimination. Today I'm using substitution method.
First name the 2 equations.
3x + y = 3 (1)
x + y = 2 (2)
Now pick one equation and express one algebra in forms of the other.
From (2),
x = 2 - y (3)
Now substitute (3) into (1),
3(2-y) + y = 3
6 - 3y + y = 3
6 - 2y = 3
6 - 3 = 2y
y = 1.5
Now substitute y = 1.5 into (2)
x + 1. 5 = 2
x = 2 - 1.5
x = 0.5
Therefore the answer is x = 0.5 and y = 1.5
Answer:
Step-by-step explanation:
Let price of milgrade gas be x and price of lawnmower gas be y.
18x + 5y=59.51
14x+y=39.75
Isolate one variable and substitute to solve for other variable.
