Simultaneous equations are where you have multiple equations, often coupled with multiple variables. An example would be x+y=2, x-y=2. To solve for x and y, both equations would have to be used simultaneously.

Another straight line equation is needed such that both simultaneous equations will intersect at one point.

Quadratic, simultaneous and straight line equations

equation

p q and p q cannot be a useful part of a system of simultaneous equations since they are the same!

Resembling, represented by, or consisting of a line or lines. Examples in maths: linear equation: A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. Typical linear equation:

You are given a system of n or more simultaneous linear equations involving n unknowns. Pick one of the unknowns, called the pivot variable. Find an equation in which it appears, called the pivot equation.

A simultaneous equation

No because it's not a simultaneous equation but some kind of algebraic expression

Simultaneous suggests at least two equations.

Another straight line equation is needed such that both simultaneous equations will intersect at one point.

Simultaneous equations have the same solutions.

Simultaneous Equations are very helpful because it can help u solve problems in real life. There are 2 ways to approach a simultaneous equation, Substitution and elimination method. As a good practice it is always good to practice your substitution method first. I wont go too advance for now but consider this question; Find two numbers whose sum is 21 and difference is 9. This question requires 2 equation to solve; thus it is call simultaneous equation. Solve: Let x be a number, and Let y be another number. x + y = 21 equation 1 x - y = 9 equation 2 Rearrange equation 2 to make equation 3(Equation 3 is just to sub into the other eqs) x = 9 + y equation 3 Sub equation 3 into 1 (9 + y) + y = 21 9 + 2y = 21 2y = 12 y = 6 First solution! Sub y = 6 into equation 2 x - 6 = 9 x = 15 Second Solution! Therefore, the numbers are 15 and 6. In a simultaneous equation (with 2 variable) there will always be 2 answers. Good luck and hope this help.
