Answer:
y =
Step-by-step explanation:
Step 1: Add -5x to both sides.
5x − 4y + −5x = 28 + −5x
−4y = −5x + 28
Step 2: Divide both sides by -4.
y =
Answer:
Step-by-step explanation:
Let's reformat both equations so that is by itself on each side:
Since we isolated to one side in both equations, we know the right-hand sides must be equal:
Solving for will give us the x-coordinate of the point of intersection:
Plugging in this x-coordinate to either of the above equations will give us the y-coordinate of the point of intersection:
Therefore, the point of intersection is
