6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
To solve this, you would normally set up a systems of equations 10x + 2y = 10 10x + 2y = 11 However, it clearly makes no sense and has no answer. To prove this mathematically, subtact the two equations. 10x - 10x = 0 2y - 2y = 0 10-11 = -1 Therefore, it is basically saying that 0 + 0 = -1 Obviously, that is incorrect, so this question has no solutions.
The value of x is 11/2

The value of x is 11/2
They intersect at the point of: (-3/2, 11/4)
The roots of the equation are [5 +/- sqrt(11)]/2 = 4.158 and 0.842
-10x = x-33 -10x-x = -33 -11x = -33 x = 11

-8 + 19 = 11
x = -11
