-6z + 2 = 3z + 4z + 28
Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z
Subtract 28 from both sides: - 26 = 13z
Divide both sides by 13: -2 = z
this can not be solved un less with another equation
A single linear equation in two variables cannot be solved.
One linear equation in two variables (x and y) cannot be solved.
It is a non-linear equation in x and y. The equation cannot be solved without further information.
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".

x = - 4 - or + the square root of 3 Solved by using the quadratic equation formula.
It can be solved by using the quadratic equation formula.
is an equation of a straight line. It cannot be solved since the solution of an equation with two unknowns (x and y) requires 2 independent equations.
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
3x + 7 = 46 is an equation. It can be solved as follows: 3x = 39 so x = 13
