Respuesta :

  x +2y = 5    multiplie by -3 => -3x -6y = -15
3x +5y = 14

-3x -6y = -15
 3x +5y = 14
------------------- assum the same terms 
 0 -y = -1
     y = 1 

x +2y = 5
x +2*1 = 5
x +2 = 5
x = 5 -2
x = 3 

x = 3
y = 1

The solution of the system of equation is x = 3 and y = 1.

System of the equation;

The relation between two variables is called a system of equations.

Given

The system of equations;

[tex]\rm x + 2y = 5 \\\\3x + 5y = 14[/tex]

From equation 1

[tex]\rm x+2y=5\\\\x=5-2y[/tex]

Substitute the values of x in equation 2

[tex]\rm 3x+5y=14\\\\3(5-2y)+5y=14\\\\15-6y+5y=14\\\\-y=14-15\\\\-y=-1\\\\y=1[/tex]

Substitute the value of y in equation 1

[tex]\rm x+2y=5\\\\x+2(1)=5\\\\x+2=5\\\\x=5-2\\\\x=3[/tex]

Hence, the solution of the system of equation is x = 3 and y = 1.
