these two bars |  | mean <u>absolute value</u>

here's how to find x

| x - 7| = 2

first apply the absolute rule

x - 7 = 2                 x - 7 = -2

in both equations add 7 on both sides

x - 7 + 7 = 2 + 7       x - 7 + 7 = -2 + 7

then simplify the expressions

x = 9                         x = 5

now combine these two solutions to get your answer

x = 9 or x = 5

hopefully my explanation helps

RESOLVER LOS SIGUIENTES SISTEMAS DE ECUACIONES APLICANDO EL METODO DE SUSTITUCION
kiruha [24]

Answer:

x = 1/2; y = 1/3

Step-by-step explanation:

2x + 3y = 2     Eq. 1

-6x + 12y = 1     Eq. 2

Eq. 1

2x + 3y = 2

2x = -3y + 2

x = -3/2 y + 1

Eq. 2

-6x + 12y = 1

De Eq. 1 sabemos que x = -3/2 y + 1

-6x + 12y = 1

-6(-3/2 y + 1) + 12y = 1

9y - 6 + 12y = 1

21y - 6 = 1

21y = 7

y = 7/21

y = 1/3

Eq. 1

2x + 3y = 2

2x + 3(1/3) = 2

2x + 1 = 2

2x = 1

x = 1/2

Respuesta: x = 1/2; y = 1/3
