For example, take these 2 equations: 2x+5y=25(eq 1) and 3x+4y=17(eq 2) First, since none of the variables have the same coefficient,you try to make them have it. How? Easy. You multiply both equations by a number till you get it. To solve, you multiply the whole first equation by 3 and the whole second equation by 2 which yields: 6x+15y=75 and 6x+8y=34. Then, you subtract the first equation from the second equation which yields: 7y=41 so y=41/7. Now you substitute in any equation:2x+5(41/7)=25 After simplification, x=-15/7. So there you go, x=-15/7 and y=41/7.

What is an equation of a non linear equation?
A non-linear equation is any equation which includes variables with a degree other than one. Therefore, any equation involving x2, x3, x4, .... would be non-linear. For example: y= 3x+2 is linear, because x and y are both degree 1 (no exponent) y= 2x2 is non-linear, because x is degree 2.
How do you solve imaginary equations?
The answer depends on the nature of the equation. Just as there are different ways of solving a linear equation with a real solution and a quadratic equation with real solutions, and other kinds of equations, there are different methods for solving different kinds of imaginary equations.
Why do you isolate the variable on one side the the equation when solving a linear equation?
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
Is y0 a linear equation?
Hard to tell because of problems with the browser. If the question is about "y = 0" the answer is YES.
What is 306g is equal too 22.5?
It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.
What are the geometric problems involving linear equation?
i want an example of geometric linear equations
How does solving a literal equation differ from solving a linear equation?
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
Why do you clear decimals when solving a linear equation?
because you just do!
How do you graph a linear equation slope intercept?
You can graph a linear equation slope intercept by solving the equation and plugging in the numbers : y=mx+b
What does it mean when the result of solving a linear equation is x equals 0?
Solving a one variable linear equation involves getting the variable on one side of the equals sign by itself. To do this one uses the properties of numbers.
How do you evaluate linear equations involving addition and subtraction?
You add or subtract, as required by the equation!
What are 3 methods to solving a system of linear equations?
u can use gauss jorden or gauss elimination method for solving linear equation u also use simple subtraction method for small linear equation also.. after that also there are many methods are available but above are most used
How can you tell if an equation has at most one solution without solving it?
You can be certain if the equation is linear, that is, of the form ax + b = 0 where a and b are constants.
What is an equation of a non linear equation?
A non-linear equation is any equation which includes variables with a degree other than one. Therefore, any equation involving x2, x3, x4, .... would be non-linear. For example: y= 3x+2 is linear, because x and y are both degree 1 (no exponent) y= 2x2 is non-linear, because x is degree 2.
Is 4x2x a linear equation?
Difficult to tell because of problems with the browser. 4x = 2x IS a linear equation whose solution is x = 0
Who discovered the systems of linear equation?
The history of linear algebra begins with Leibniz in 1693 who studied determinants. In 1750, Cramer invented a rule (Cramer's rule) for solving linear systems.
