only one value will make the equation true:
2x = 5
x=5/2
x=2.5
To check this, you substitute the values for x and y into the equation. At (1,2) x equals 1 and y equals 2 so substituting this in we get: x + 2y = 1 + 2(2) = 1 + 4 = 5 And since it equals 5 like in the original equation the point is represented by it.
A variable like "x" can have any value. If you have a complete equation, like 9x + 12 = 100, a specific value of x will make the equation true; other values will make it false. But here, you don't have an equation, so any value will do for x.
Addition works because like all mathmatics as long as you know 1/2 of the equation, answer, and type of equation (addition,subtraction,multiplication, or division) there is only 1 answer.
An equation is like this: 34+76=110 If there's an equals sign in the problem then it's an equation. -Monicalovesu
No, y=8 is a fixed value. A linear equation would look something like y=x+8 - That would produce a straight line graph if the values of x & y were plotted against each other on a graph.

No. It is only true for one value of x so it is an equation. An identity must be true for all values of x. An identity equation is like saying "in other words ... ".

Literal equation refers to an equation in which the variables represent known values. This type of equation allows the representation of things like distance, interest, time, and slope as variables in an equation.

The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
To find what plus what equals 325, we can set up an equation as x + y = 325. Since both x and y are unknowns, there are multiple possible combinations that could satisfy this equation. Some examples include 200 + 125 = 325, 150 + 175 = 325, or even decimal values like 162.5 + 162.5 = 325.
