x + 2 = -2x + 2
Add 2x to each side of the equation:
3x + 2 = 2
Subtract 2 from each side:
3x = 0
Divide each side by 3:
x = 0
The equation is a true statement only if x=0.
this can not be solved un less with another equation
A single linear equation in two variables cannot be solved.
x = - 4 - or + the square root of 3 Solved by using the quadratic equation formula.
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
-2x plus 3y equals 1
this can not be solved un less with another equation
A single linear equation in two variables cannot be solved.
x = - 4 - or + the square root of 3 Solved by using the quadratic equation formula.
It is a single linear equation in two unknown variables. It cannot be solved without additional information.
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
-2x plus 3y equals 1
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 is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13
It cannot be solved because the discriminant of the quadratic equation is less than zero
y = 2x + 1 IS a linear equation!
