To solve the equation y = x^2 - 3x - 20 using systems, you can set up a system of equations by substituting y with x^2 - 3x - 20. This gives you the equation x^2 - 3x - 20 = 0. You can then solve this quadratic equation using factoring, the quadratic formula, or completing the square to find the values of x. Once you have the values of x, you can substitute them back into the original equation to find the corresponding values of y.

How do you solve 0 equals x squared minus ten x plus 16?
Solve using the quadratic formula
What 4x y14 and 2x y8 solve using substitution?
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
Solve using the rule of 72 rate equals 4 percent years equals 18 fv equals 8000 solve for pv?
Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
How do you solve y equals 2x-6 and 3x plus y equals 4 using the elimination method?
(2,-2)
Solve using substitution x plus y equals 3 and y equals 9?
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
