If: 12 = 2y+x then y = -1/2x+6
So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
x = -5
It is the commutative property of addition.
(5, 1)
-10
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
They are straight lines.
They are parallel lines.
Perpendiculat straight lines.
perpendicular
It is not one, but they are two perpendicular lines.
it equals 72. just do 12 X 6
it equals 70
12 plus 9 equals 21.
zero solutions. If you plot these two lines, you will see that they are parallel and do not intersect.
12+12
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
12 + 10 + 11 equals 33
