If you mean: 2x+5+3x = 25 then the value of x works out as 4
a solution
It is an equation and the value of a is -1 because -6 times -1 = 6
It is an equation in the form of: 3x+5 = 20 and the value of x works out as 5
None because the numbers 4, 2 and 6 can't be considered to be an equation.
It is called the "soulltion set"
5.0
There is no value of x that satisfies the equation. You may be missing an operator (+. - sign).
It is the solution of the given equation.
5a - 1 = a - 7 4a = -6 a = -1.5
a solution
It is an equation and the value of a is -1 because -6 times -1 = 6
If you found the value of x that is a solution to an equation, you want to substitute that value back into the original equation, to check that it indeed satisfies the equation. If it does not satisfy the equation, then you made an error in your calculations, and you need to rework the problem.
-3/2
Only one value of x satisfies this [x = 3], but y is not specified, so y can be any value. In a 2 dimensional plane, this would be a vertical line at x = 3
y=0. note. this is a very strange "curve". If y=0 then any value of x satisfies the equation, leading to a curve straight along the y axis. For any non-zero value of y the curve simplifies to y = -x. The curve is not differentiable at the origin.
In mathematics, a solution refers to a value or set of values that satisfies an equation, inequality, or system of equations. It is the value or values that make the equation or inequality true.
Answer is 5.4 percent because you want equvailent fractions in the equation so thefore you times the decimal value by 100 so equation is 100 times 00.54 equals 5.4 percent. THIS IS THE ANSWER
