eg "5x² + 2x = 5" should be written as "5 times x power 2 plus 2x equals 5".
x + y = 18 x - y = -4
( 3,10)
5x-2y = 4 2(3x+y = 9) Multiply all terms in the second equation by 2: 5x-2y = 4 6x+2y = 18 Add the equations together: 11x = 22 Divide both sides by 11 to find the value of x: x = 2 Substitute the value of x into the original equations to find the value of y: Therefore: x = 2 and y = 3
y = 4x-8 and y = 2x+10 4x-8 = 2x+10 4x-2x = 10+8 2x = 18 x = 9 Substitute the value of x into the original equations to find the value of y: Therefore: x = 9 and y = 28
Let's call the two numbers x and y. We know that x + y = 18 and x - y = 2. We can solve this system of equations by adding the two equations together to eliminate y, which gives us 2x = 20. Dividing both sides by 2, we find that x = 10. Substituting this value back into one of the equations, we can solve for y and find that y = 8. Therefore, the two numbers are 10 and 8.
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
3y+18=7y-6
Value is what something is worth. Like the value of 18 is 18. Absolute Value is the distance from the number to 0. An example of this is the Absolute Value of -18 is 18.
It means that at least one of the equations can be expressed as a linear combination of some of the other equations. A linear combination of equations is the addition (or subtraction) of equations. And since an equation can be added several times, it includes multiples of equations. For example, if you have x + 2y = 3 and 2x + y = 4 Then adding 2 times the first and 3 times the second gives 8x + 7y = 18 This is, therefore, dependent on the other 2. If you have n unknown variables, there will be a unique solution if, and only if, you must have a set of n independent linear equations.

x = -3/5 and y = -24/5
