How do you solve a fraction equation?
To solve a fractional equation, first eliminate the fractions by multiplying both sides of the equation by the least common denominator (LCD) of every term. We can do this because multiplying both sides of an equation by the same quantity (the LCD in this case) does not unbalance the equation.
Can we solve equations in calculator?
Basic calculators are great for solving simple equations with one or two variables, but scientific calculators allow you to input a problem that has an order of operations. If you enter one of these equations into a regular calculator, it won’t be able to correctly determine which numbers should be addressed first.

How do I find a quadratic equation given 2 points and no vertex?
How do i find the equation of a parabola given 2 points and the axis of symmetry, but no vertex?
- Using the vertex form of a parabola f(x) = a(x – h)2 + k where (h,k) is the vertex of the parabola.
- The axis of symmetry is x = 0 so h also equals 0.
- a = 1.
- Substituting the a value into the first equation of the linear system:
