y = 2x - 3
y = -x + 3
2x - 3 = -x + 3
Add 3 to each side of the equation:
2x = -x + 6
Add 'x' to each side:
3x = 6
Divide each side by 3:
x = 2
Substitute into either original given equation:
y = 2x - 3 = 2(2) - 3 = 4 - 3 = 1
The point of intersection / common solution / ordered pair is (2, 1) .
x = 3 and y = 4 so the lines intersect at (3, 4)
(2x + 3)(2x + 3)
2x = x+3 2x-x = 3 x = 3
(0, -3)
2x = 4x + 3 -2x = 3 x = -3 / 2
The ordered pair is (1, 3).
(x, y) = (3, 2)
x = 3 and y = 4 so the lines intersect at (3, 4)
There are an infinite number of ordered pairs. (-5, -7) is one pair
The ordered triple is (x, y, z) = (1, -1, -2)
(2x + 3)(2x + 3)
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2x = x+3 2x-x = 3 x = 3
(0, -3)

the converse of this conditional is true
2x = 4x + 3 -2x = 3 x = -3 / 2
