Answer:
Point form = (3, 7)
Equation form = x = 3, y = 7
Explanation:
First we want to replace the occurrences of y in 3x - 4y = -19 with x + 4
3x - 4 (x+4) = -19
Next we simplify the left side.
3x - 4x - 16 = -19
Subtract 4x from 3x
-x - 16 = -19
Then we want to solve for x in -x - 16 = -19
So lets move all terms that do not contain x to the right side.
-x = -19 + 16
Then add
-x = -3
Then we want to divide each term in -x = -3 by -1
y = 3
y = x + 4
Now we want to replace all occurrences of x with 3 in each equation.
y = (3) + 4
x = 3
Add 3 and 4 and we get 7.
Therefore our solution as an ordered pair is (3, 7).
Equation form = x = 3, y = 7.
