Respuesta :

x + 8 = 4x - 1
3x = 9
x = 3

y = 3 + 8 = 11

Answer:

x = 3, y = 11

Step-by-step explanation:

Use substitution:

[tex]x + 8 = 4x-1\\[/tex]

Subtract x from both sides

[tex]8 = 3x - 1[/tex]

Add 1 to both sides

[tex]9 = 3x[/tex]

Divide both sides by 3

[tex]x = 3[/tex]

Now substitute x = 3 into the equation y = x + 8

[tex]y = 3 + 8[/tex]

[tex]y = 11[/tex]

That means the solution is x = 3, y = 11
