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]
