3x - 12x = 108 - 162
9x = 54
x = 6
y = 10

2nd one is 36xy, see other question.

Solve the system of equations. y=x+6y=x2+8x+16
Semenov [28]

Answer:

(- 2 ; 4) or (-5 ; 1)

Step-by-step explanation:

y = x + 6

y = x² + 8x + 16

x + 6 = x² + 8x + 16

x² + 8x + 16 - x - 6 = 0

x² + 7x + 10 = 0

x² + 5x + 2x + 10 = 0

x(x + 5) + 2(x + 5) = 0

(x + 2)(x + 5) = 0

x + 2 = 0 => x₁ = - 2

x + 5 = 0 => x₂ = - 5

y₁ = - 2 + 6 => y₁ = 4

y₂ = - 5 + 6 => y₂ = 1
