How do you know that solutions using substitution gives the answer ot the system of equations?
Here's a mark you use in your math every day, and right now, you have to stop
for a second and understand and accept what it really means:
=See that ? That's the "equals" sign. When you write (one quantity) = (another quantity),that means that honestly and truly, those two quantities are not only 'equivalent', but
literally equal in every way. Either one can do anything and everything that the other
one can do, and wherever you see one of them, you can stick the other one in its place,
because they're equal in every way.
That's why substitution is a legitimate operation. If a statement is true before substitution,
it's still true after substitution.
What else can I help you with?
What do you call the graphs that intersect at exactly one point which gives solution of the system?
They are straight line graphs that work out the solutions of 2 equations or simultaneous equations
Is (-1 1) a solution to this system of equations?
The values for which the equations are solved. Graphically the intersection of the lines that are the solutions to the individual equations. The link below gives some explanations. The equations themselves will have to be given for a solution to be found.
In substitution method x plus 2y13?
It seems like there's a typo in your equation. If you meant (x + 2y = 13), you can use the substitution method by solving for (x) in terms of (y). Rearranging gives (x = 13 - 2y). You can then substitute this expression for (x) into another equation if you're solving a system of equations.
What are the solutions of the simultaneous equations of x squared -xy -y squared equals -11 and 2x plus y equals 1?
1st equation: x^2 -xy -y squared = -11 2nd equation: 2x+y = 1 Combining the the two equations together gives: -x^2 +3x +10 = 0 Solving the above quadratic equation: x = 5 or x = -2 Solutions by substitution: (5, -9) and (-2, 5)
What is numerical solutions of nonlinear equations?
Linear equations, if they have a solution, can be solved analytically. On the other hand, it may not always be possible to find a solution to nonlinear equations. This is where you use various numerical methods (eg Newton-Raphson) to work from one approximate numerical solution to a better solution. This iterative procedure, if properly applied, gives accurate numerical solutions to nonlinear equations. But as mentioned above, they are not arrived at analytically.
How do you know that substitution gives the answer to a system of questions?
Substitution solves a system of equations by isolating one variable and substituting its value into the other equations, which simplifies the problem. This method ensures that the relationships defined by the equations are maintained, leading to a consistent solution. Once you find values for all variables, you can verify them by substituting back into the original equations to confirm they satisfy all conditions. Thus, substitution not only provides answers but also confirms their validity.
How do you know that substitution gives the answer to a system of equations?
You put in the answers you got for your variables into one of the equations. If it gives you the correct answer then you solved it, if it's different then either it doesn't work or one of the steps wasn't completed correctly or at all.

Solve this system of equations using substitution. Put your answer in ordered pair form (x y). x plus 7y 39 3x - 2y 2?
To solve the system of equations given by ( x + 7y = 39 ) and ( 3x - 2y = 2 ) using substitution, we can first solve the first equation for ( x ): ( x = 39 - 7y ). Substituting this into the second equation gives ( 3(39 - 7y) - 2y = 2 ). Simplifying this results in ( 117 - 21y - 2y = 2 ), or ( 117 - 23y = 2 ), leading to ( 23y = 115 ) and ( y = 5 ). Plugging ( y = 5 ) back into ( x = 39 - 7(5) ) gives ( x = 4 ). Thus, the solution in ordered pair form is ( (4, 5) ).
Describe the solution to the system of equations 5x - y equals 8 and 25x-5y equals 32?
Substitution method: from first equation y = 5x - 8. In the second equation this gives 25x - 5(5x - 8) = 32 ie 25x - 25x + 40 = 32 ie 40 = 32 which is not possible, so the system has no solution. Multiplication method: first equation times 5 gives 25x - 5y = 40, but second equation gives 32 as the value of the identical expression. No solution.
Elimination gives the solution to the system of equations when each row has nothing but zeros and a single 1 to the left of the thin line?
