It's a whimsical suggestion of an algebraic equation.
It has no solution, because there isn't enough information to solve for 'x' or 'y'.
In order to solve for the numerical value of two unknowns, two equations are required.
it equals 13X.
x=1
What is the answer to 2x - 5x plus 6.3 equals -14.4?
-2x plus 3y equals 1
x = 0
X=7
NM equals 2x + 1, as stated in the question!
x=0
8x-7 plus 2x equals 6 plus 5x plus 2?
3x
2x+3x = 5x
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
