y=x2 and y=lnx are two examples of nonlinear equations.
What is the solution set for the equations x-y=2 and -x+y=2
Linear equations or inequalities describe points x y that lie on a circle.
42
The basic idea here is to look at both equations and solve for either x or y in one of the equations. Then plug the known value into the second equation and solve for the other variable.

The expressions "xx" and "xy" suggest that you might be referring to two equations involving the variables x and y. If you meant to write the equations as (y = xx) (or (y = x^2)) and (y = xy) (or (y = x \cdot y)), they can be rewritten into a system of equations. However, without clearer definitions of these expressions, it's difficult to provide a precise system. Please clarify the equations for a more accurate response.
if y = xa then a = logxy
x + y = 43 x - y = 13 2x = 56 x = 28 28 + y = 43 y - 28 = 43 = 15 I'm sure you meant: y = 43 - 28 = 15
Here is an example:x + y = 0x + y = 1If you draw the graph for the two equations, you'll have two parallel lines.Here is an example:x + y = 0x + y = 1If you draw the graph for the two equations, you'll have two parallel lines.Here is an example:x + y = 0x + y = 1If you draw the graph for the two equations, you'll have two parallel lines.Here is an example:x + y = 0x + y = 1If you draw the graph for the two equations, you'll have two parallel lines.
Without any equality signs they can't be considered to be equations.
If 2 equations are perpendicular to one another they can have different y-intercepts, depending on how they are situated on a (x,y) graph.
1. Linear Equations y= mx + b (standard form of linear equation) 2. Quadratic Equations y= ax^2+bx+c 3. Exponential Equations y= ab^x 4. Cubic Equations y=ax^3+ bx^2+cx+d 5. Quartic Equations y= ax^4+ bx^3+ cx^2+ dx+ e 6. Equation of a circle (x-h)^2+(y-k)^2= r^2 7. Constant equation y= 9 (basically y has to equal a number for it to be a constant equation). 8. Proportional equations y=kx; y= k/x, etc.
This is easily solved by using two equations in 2 unknowns and solving the system. x + y = 111 x - y = 43 If have not yet had the pleasure of studying algebra and the answer is important to you, you could hope the numbers are positive integers and try all pair of numbers whose sum is 43: 1,42 2,41 3,40 and so on, until you find a pair whose difference is 43.
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.
If "equations-" is intended to be "equations", the answer is y = -2. If the first equation is meant to start with -3x, the answer is y = 0.2
It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept
