Given, that
4x + 6 = 6x - 12; then,
(6x - 12) - (4x + 6) = 0,
2x - 18 = 0, and
2x = 18.
Thus, x = 9.
Checking, we substitute 9 for x in the equation:
4(9) + 6= 6(9) - 12; whence,
36 + 6 = 54 - 12, and
42 = 42, which is patently true.
What this means is that the original equation is true exactly when x = 9; otherwise, it is false. We call 'x = 9' the solution to the given equation.

What does x equal in 2x plus 6-6x equals 30?
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
3x2 plus 4x-15 equals 0?
no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
What is the answer to 6-x plus 12 equals 10x plus 7?
5=4x 1.25=x
Combine 8x plus 5z minus 4x plus 3z plus 6?
8x + 5z - 4x + 3z + 6 = 8x - 4x + 5z + 3z - 6 = 4x + 8z - 6
If 8x plus 5x plus 2x plus 4x equals 114 then what would 5x plus 3 equal?
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
If-4x plus 6 equals 38 what do x equals?
if -4x+6=38 what x=
-10x-6 plus 4x equals -4x plus 8?
-6x-6 -or- -6(x+1)
How tosolve 4x plus 2 plus 6 equals 2?
4x + 2 + 6 = 2 4x + 8 = 2 4x = -6 x = -6/4 = -3/2
4x plus 32 equals -4x plus 16 x equals?
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
4x plus y-6 equals 0?
Then the straight line equation is: y = -4x+6
3x plus 4x plus 6 equals 41?
x=5
6x plus 4 equals x plus 12 plus 4x-6?
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
If x equals 8 then 4x plus 6 equals 46?
No. Substitute the value 8 for x, and you have 4x +6 = 4(8) +6 = 32 +6 = 38.
What is the ordered pair for 2y equals 4x plus 8 and 4y equals 4x plus 20?
x = 1 and y = 6 so the lines intersect at the point (1, 6)
What is 6 -2x plus 8 plus 4x equals 8?
