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
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.
If: 4x+(-12) = 8 then 4x = 20 and x = 5
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
