6x + 3 = x + 8
For equations such as this (it is called a linear equation as it contains only the first power of the unknown quantity) group all the terms containing the unknown on one side of the equation (preferably the left) and all the other terms on the other side.
Step 1) Subtract x from both sides
6x -x + 3 = x - x + 8 : 5x + 3 = 8
Step 2) Subtract 3 from both sides
5x + 3 - 3 = 8 - 3 : 5x = 5
Step 3) Divide both sides by 5
5x/5 = 5/5 : x = 1
The solution to this problem is x = 1
6x + 18 = 54 6x = 54 - 18 6x = 36 x = 36 ÷6 x = 6
Solving the equation for "y" gives you the slope-intercept form.

2sin2(6x) + 3sin(6x) + 1 = 0 Solving the quadratic, sin(6x) = -1 or sin (6x) = -0.5 sin(6x) = -1 => 6x = 45+60n degrees for integer n sin(6x) = -0.5 => 6x = 35+60n or 55+60n degrees for integer n.
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.

The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x+4=52 6x=48 x=8
It is: 3x2+6x-11 = 0
