If you mean: 4 = 2x then the value of x = 2
Y - 2x +4 is an expression which cannot be simplified. Since it is neither an equation nor an inequality, it cannot be solved.
y -2x when solved mathematically would remain y - 2x.
The problem can be written as:2x - 6 = 4and solved as:2x - 6 = 4+6 = +6 [adding 6 to both sides]2x = 10(2x)/2 = (10)/2 [dividing both sides by 2]x = 5
It can be simplified to 2x^2 +x -6 and factored to (2x-3)(x+2)
There is no equation nor inequality in the question so there is nothing which can be solved.
2x - 3y = 4This can't be solved, although you can express each variable in terms of the other.x = (4-3y)/2y = (2x-4)/3
Y - 2x +4 is an expression which cannot be simplified. Since it is neither an equation nor an inequality, it cannot be solved.
5x^(2) + 2x - 4 = 2x^(2) Hence 3x^(2) + 2x - 4 = 0 Now apply the Quadratic Equation. x = { - 2 +/- sqrt[2^(2) - 4(3)(-4)]} / 2(3) x = {-2 +/- sqrt[4 + 48]} / 6 x = { -2 +/- sqrt(50_] / 6 x = { -2 +/-5sqrt(2)} / 6 x = (-2 - 5sqrt(2))/ 6 & x = (-2 + 5sqrt(2))/ 6 Since the square root of '2' is an Irrational Number. (decimals go to infinity, the answer is left in 'surd' form .
y -2x when solved mathematically would remain y - 2x.
The problem can be written as:2x - 6 = 4and solved as:2x - 6 = 4+6 = +6 [adding 6 to both sides]2x = 10(2x)/2 = (10)/2 [dividing both sides by 2]x = 5
It can be simplified to 2x^2 +x -6 and factored to (2x-3)(x+2)

4x+3y=20 / 2x-3y=4 ..... In this case x=4 and y=4/3
4
It is: (2x-5)(2x-5) = 2.5 square cm when solved as a quadratic equation
There appears to be no equation in the question: only some disjoint expressions. Expressions cannot be solved.
