Step-by-step explanation:
So we have the equation:
First, subtract 9 from both sides:
Divide both sides by -4:
Definition of Absolute Value:
Subtract 3 from both sides:
Divide both sides by 5:
And we're done!
For this case we have the following system of equations:
-4x + 5y = 8
6x - y = 11
The solution is the ordered pair where both functions intersect.
In this case, the point of intersection is:
(x, y) = (5/2, 7/2)
Answer:
(x, y) = (5/2, 7/2)
