6x - 3y = 3 , 5x - 5y = 10

Respuesta :

By elimination, the solution of the system of equations, 6x - 3y = 3 and 5x - 5y = 10, is (-1 , -3).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

First, simplify both equations by dividing the first equation by 3 and the second equation by 5.

6x - 3y = 3 ⇒ 2x - y = 1     (equation 1)

5x - 5y = 10 ⇒ x - y = 2     (equation 2)

Use the elimination method since subtracting the two equations will eliminate the variable y.

2x - y = 1     (equation 1)

 x - y = 2     (equation 2)

x        = -1

x = -1

Substitute the value of x to any of the two equation and solve for y.

6x - 3y = 3     (equation 1)

6(-1) - 3y = 3

-3y = 3 + 6

-3y = 9

y = -3

Hence, the solution of the system of equations is (-1 , -3).
