WebA linear equation in one variable is an equation of degree one and has only one variable term. It is of the form 'ax+b = 0', where 'a' is a non zero number and 'x' is a variable. By solving linear equations in one variable, we get only one solution for the given variable. An example for this is 3x - 6 = 0. WebDivide by 3: x = (9+6)/3 Now we have x = something, and a short calculation reveals that x = 5 Like a Puzzle In fact, solving an equation is just like solving a puzzle. And like …

WebWhen there is only one variable, polynomial equations have the form P(x) = 0, where P is a polynomial, and linear equations have the form ax + b = 0, where a and b are parameters. To solve equations from either family, one uses algorithmic or geometric techniques that originate from linear algebra or mathematical analysis. WebThen do the same for the denominator on the right and the numerator on the left. These new expressions will be equal to each other. For your example, it will look like: (x-9) (-2)= (x) (7) Distribute/multiply to get: -2x + 18 = 7x. Add 2x to both sides to gather your variables: 18 = 9x. Divide both sides by 9.
