How many values of x and y satisfy the equations 2x plus 6y equals 12 and 3x plus 9y equals 18?

2X + 6Y = 12
3X + 9Y = 18
try elimination
- 3(2X + 6Y = 12)
2(3X + 9Y = 18)
- 6X - 18Y = - 36
6X + 18Y = 36
=================
I will say this system is dependent and an infinite number of solutions can be found.

What is the equation that always equals 2?
well there are many equations actually.
How many triangles are there that satisfy the conditions a equals 13 b equals 9 A equals 62?
Two. One in which C is acute and one where it is obtuse.
What linear equation equals 91?
There are many linear equations that equal 91! For instance, 2x + 4 = 91 and 3x + 5 = 91 Too many equations.. The question needs revision!.
How many values does l have when n equals 4?
It depends on how I is defined.
How many solutions do the following equations have in common 8y equals -75x - 22 and 75x equals -8y plus 22?
I notice that the ratio of the y-coefficient to the x-coefficient is the same in both equations. I think that's enough to tell me that their graphs are parallel. So they don't intersect, and viewed as a pair of simultaneous equations, they have no solution.
What does it mean to solve a system of linear equations?
Find values for each of the unknown variables (or at least as many as is possible for the system) that satisfy all the equations.
How many different combinations of x-values and y-values could satisfy the equation - x plus y equals 5?
10.
What is the equation that always equals 2?
well there are many equations actually.
How do you solve 3x plus 2y equals 5?
You cannot solve this equation without some more information. The value of y depends upon the value of x, but they could take infinitely many different values. Maybe this is just one of a pair of simultaneous equations? If so, you need both equations to find values for x and y.
How many solutions does this system of equations have 2x-3y equals -14 4x-6y equals -28?
The equations are identical in value, ie the second is merely twice the first...

What is Simultaneous Equations?
Simultaneous equation is nothing: it cannot exist.A system of simultaneous equations is a set of 2 or more equations with a number of variables. A solution to the system is a set of values for the variables such that when the variables are replaced by these values, each one of the equations is true.The equations may be linear or of any mathematical form. There may by none, one or more - including infinitely many - solutions to a system of simultaneous equations.
You are given two equations which are both true and you are asked to solve for both x and y you plan to solve this set of equations by substituting part of one equation into the other so you end up wi?
Many equations can be plotted as a line or other curve in the x-y plane. If you have two equations and you plot the curve (or line) for each one. If the curves (or lines) intersect at one or more points, then the (x,y) coordinates for the intersection points will also be the x and y values which satisfy both equations to be true at the same time.
What is the value of x and y when x2 divided by y2 equals 45?
There could be a few values. 45 divided by 1 could work, and X=root 45 and Y=1 There are two variables, so two equations would be needed to determine the values. Otherwise, there are many solutions.
Solve this system of equations using the addition method x plus y equals 6?
When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations.
