Answer :

Answer:

x=4, y=5

Step-by-step explanation:

[tex]\left \{ {{6x+y=29} \atop {3x-y=7}} \right. \\\\[/tex]

1. (Find the value of x) Add both equations together.

[tex]9x=36[/tex]

Divide both sides by 9.

[tex]x=4[/tex]

2. (Find the value of y) Replace x as 4 in the first equation.

[tex]6*4+y=29\\[/tex]

[tex]24+y=29[/tex]

Subtract 24 from both sides.

[tex]y=29-24\\y=5[/tex]

Answer:

(4, 5) [tex]x=4, y=5[/tex]
