If you mean: y = 6x-4 and y = 7x-7 then by substitution x = 3 and y = 14
2x+7y=29 x=37-8y
3x+y = 10 y = x-2 Substitute the value of y into the top equation: 3x+x-2 = 10 => 4x = 10+2 => 4x = 12 => x = 3 Substitute the value of x into the original equations to find the value of y: So: x = 3 and y = 1
Without any equality signs they can't be considered to be equations. But if you mean: x+2y =12 and y = x+3 then the solution is as follows x+2y = 12 -x+y = 3 Adding the equations together: 3y = 15 and y = 5 By substitution: x = 2 Solution: x = 2 and y = 5
It is not possible to know exactly what the question is because the browser used by this site is almost totally useless for mathematical questions: it rejects most symbols. If the equations are 2y + 2x = 20 and y - 2x = 4,then the solution is (2, 8).
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
the solution to the system of equations 6x + 7y = 20 and y = 2x is (x, y) = (1, 2)
You can solve the system of equations with three variables using the substitute method, or using matrix operations.

Henry A. Nogrady has written: 'A new method for the solution of cubic equations'
2x+7y=29 x=37-8y
Euler's Method (see related link) can diverge from the real solution if the step size is chosen badly, or for certain types of differential equations.
there are three methods: combination, substitution and decomposition.
3x+y = 10 y = x-2 Substitute the value of y into the top equation: 3x+x-2 = 10 => 4x = 10+2 => 4x = 12 => x = 3 Substitute the value of x into the original equations to find the value of y: So: x = 3 and y = 1
There are many equations for which there is no method for obtaining an exact solution. In such circumstances, an efficient trial and error method may be the only way.
