faust18 [17]

Answer:

y = 3

x = -4

Step-by-step explanation:

Hopefully the first equation is x + 3y = 5

x = 5 - 3y

Plug in:

-2(5 - 3y) + 2y = 14

tankabanditka [31]

Answer:

x = 10°

z = 66°

Step-by-step explanation:

(9x - 24)° + (12x - 6)°  = 180°\\21x° - 30° = 180° \\ 21 x° = 180°  +  30° \\ 21x° = 210° \\ x° =  \frac{180°}{30°}  \\ x° = 10°

z° = 9x - 24 ( vertically opposite )

z° = 9(10) - 24

z° = 90 - 24

z° = 66°
