Find the value of X in triangles **by subtracting known angle measurements from 180 degrees**. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.

## How do u find the value of x?

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

## How do you work out X?

Isolate “x” on one side of the algebraic equation by subtracting the sum that appears on the same side of the equation as the “x.” For example, in the equation “x + 5 = 12”, rewrite the equation as “x = 12 – 5” and solve for “x.” The solution is “x = 7.”

## What does solve for X mean?

What Does Solve for x Mean? Solve for x means finding the value of x for which the equation holds true. i.e when we find the value of x and substitute in the equation, we should get L.H.S = R.H.S. If I ask you to solve the equation ‘x + 1 = 2’ that would mean finding some value for x that satisfies the equation.

## What is the value X?

more The letter “x” is often used in algebra to mean a value that is not yet known. It is called a “variable” or sometimes an “unknown”. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn’t have to be “x”, it could be “y”, “w” or any letter, name or symbol.
