Answer 2

Vamos hallar el valor de X de cada una de las ecuaciones

¿Que son las ecuaciones?

Las ecuaciones son expresiones matemáticas que combinan símbolos, incógnitas y números, utilizadas para resolver problemas.

• Numero 1

X + 3(x - 1) = 6 - 4(2x + 3)

X + 3X - 3 = 6 -8X - 12

4X + 8X = 3 + 6 - 12

12X = - 3

X = -3/12

X = -1/4

• Numero 2

5(x - 1) + 16(2x + 3) = 3(2x - 7) - X

5X - 5 + 32X + 48 = 6X - 21 - X

5X + 32X - 6X + X = 5 - 48 - 21

32X = -64

X = -64/32

X = -2

• Numero 3

2(3x + 3) - 4(5x – 3) = x(x – 3) – x(x + 5)

6X + 6 -20X + 12 = X^2 - 3X - X^2 + 5

6X - 20X + 3X = - 6 - 12 + 5

11X = -13

X = -13/11

• Numero 4

184 - 7(2x + 5) = 301 + 6(x - 1) - 6

184 - 14X + 35 = 301 +6X - 6 - 6

-14X - 6X = -184 - 35 + 301 - 6 - 6

-20X = 70

X = -70/20

X = -7/2

• Numero 5

7(18 - x) – 6(3 – 5x) = -(7x+9) – 3(2x + 5) -12

126 -7X - 18 + 30X = -7X - 9 -6X - 15 - 12

-7X + 30X + 7X + 6X = - 126 +18 -9 - 15 -12

36X = -144

X = -144/36

X = -4

• Numero 6

3x(x – 3) + 5(x + 7) – x(x + 1) - 2(x2 + 7) + 4 = 0

3X^2 - 9X + 5X + 35 - X^2 - X - 2X^2 - 14 + 4 = 0

(3X^2 -X^2 - 2X^2) + (-9X + 5X - X) + (35 - 14 + 4) = 0

-5X + 25 = 0

-5X = - 25

X = 25/5

X = 5
