Solve using substitution
y= -8x-6
y= -3x +4


Sagot :

Given :

y= -8x-6

y= -3x +4

By solving it, we get,

-8x-6 = -3x+4

[tex] = > x = - 2[/tex]

Substituting the value of "x" in second given equation,

[tex]y = - 3x + 4[/tex]

[tex] = > y = - 3 \times ( - 2) + 4[/tex]

By solving it, we get,

[tex]y = 10[/tex]

Hence, the values are :-

[tex]x = - 2 \\ y = 10[/tex]
