x-14 = 20 x = 20+14 x = 34
Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.

why will the equations x+14=37 and x-14=37 have different solutions for x
It is not possible to solve one equation in two unknowns (x and y). Two independent equations are required.
Strangely enough, it is y = x - 14
It is a linear equation in the variables x and y.
3x - 4y = 14 is a linear equation in two variables. It is also the equation of line.
A single linear equation in two variables cannot be solved.
4x + 10 = 14 4x = 4 x = 1

3d + 14 = 11 is the equation.
An equation.
[ 8x - 2 = 14 ] is the equation.[ x = 2 ] is the solution to the equation.
It is an equation because: a = 6

-4r+6=14 isn't an inequality, its a linear equation. Anyway... -4r+6=14 (-6) -4r=8 (/4) -r=2 (x-1) r=-2
