6x + 3 = 2x + 5 4x = 2 x=1/2

x2 + 6x + 12 = 0 x2 + 6x + 9 = -3 (x + 3)2 = -3 x + 3 = ± √-3 x = -3 ± i√3

It is an equation and the value of x is 4
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
6x plus 3 equals to 8x plus 14 would lead to x = - 5.5.
x = -3
y=(6x-5)/3
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
9x + 3 - 6x - 2 = 3x + 1
6x + 2 = 6 6x = 4 x = 2/3
6x + 3 = 2x + 5 4x = 2 x=1/2
It is: 3x2+6x-11 = 0
x=-6,5
-15 = 6x + 3 - 3-15 = 6x (3 - 3 = 0)-2.5 = x (-15/6)
