(2, -1)
y = 3X - 1
y = 3x + 1
If: 3x+5 = 4x+1 Then: x = 4
(1, 1)
42x + 1 = 8x - 1Subtract 1 from each side:42x = 8x - 2Subtract 8x from each side:34x = -2Divide each side by 34:x = -2/34 = -1/17
x + 2 = 3x-1 -2x = -3x = 1,5
It is called the commutative property, a + b = b + a
1
0 because X= -1
2x+5=3x+1 -x=-4 x=4
3x(2x + 1)
