Answer 1

Respuesta:

a. 6⅓

b. 1 1/14

c. 3⅕

d. -⅙

e. 6⅚

f. -⅗

Explicación paso a paso:

a. 7(x) – 7(5) – x = 3

7x – 35 – x = 3

7x – x = 3 + 35

6x = 38

x = 38/6 = 19/3 = 6⅓

b. -3(2x) – -3(5) – 5x = 3x

-6x + 15 – 5x = 3x

-11x + 15 = 3x

15 = 3x + 11x

15 = 14x

x = 15/14 = 1 1/14

c. 7(x) – 7(2) – 6x + 1 = 3 – 4x

7x – 14 – 6x + 1 = 3 – 4x

x – 13 = 3 – 4x

5x = 16

x = 16/5 = 3⅕

d. 4x + 2(2x) – 2(5) = 1(x) – 1(3) – 1(8) – 1(-x)

4x + 4x – 10 = x – 3 – 8 + x

8x – 10 = -11 + 2x

8x – 2x = -11 + 10

6x = -1

x = -⅙

e. 3 + 8(6) + 8 (-x) = -2(x) – -2(5)

3 + 48 + -8x = -2x + 10

51 – 8x = 10 – 2x

51 – 10 = 8x – 2x

41 = 6x

x = 41/6 = 6⅚

f. 9x – 2(x) – 2 (-4x) = 3x – 2(3) – 2(-x)

9x – 2x + 8x = 3x – 6 + 2x

15x = 5x – 6

15x – 5x = -6

10x = -6

x = -6/10 = -⅗
