2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
3.5
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
No. They are parallel.
It equals 8x+12

x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
No. They are parallel.
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
-1
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
x = -2 and y = 3
(2x + 3)(2x + 3)
