Answer 2

Hola!

Explicación paso a paso:

1)

$2x = x + 10 \\ 2x - x = 10 \\ x = 10$

2)

$130 + x + x = 180 \\ 2x = 180 - 130 \\ 2x = 50 \\ x = 25$

3)

$x + 120 = 180 \\ x = 180 - 120 \\ x = 60$

4)

$90 + a = 110 \\ a = 110 - 90 \\ a = 20 \\ \\ x + 110 + a = 180 \\ x + 110 + 20 = 180 \\ x = 180 - 130 \\ x = 50$

5)

$x + x + x = 90 \\ 3x = 90 \\ x = 30$

6)

$x + x + x = 360 \\ 3x = 360 \\ x = 120$

7)

$x + 120 + 2x + 150 = 360 \\ 3x + 270 = 360 \\ 3x = 360 - 270 \\ 3x = 90 \\ x = 30$

8)

$x + x + 4x + (x + 10) + (x + 10) = 180 \\ 6x + x + 10 + x + 10 = 180 \\ 8x + 20 = 180 \\ 8x = 180 - 20 \\ 8x = 160 \\ x = 20$

9)

$37 +90 + x = 180\\ x = 180 - 90 - 37 \\ x = 53$

10)

$110 + x + 2x + (x + 30) + 100 = 360 \\ 4x = 360 - 30 - 210 \\ 4x = 120 \\ x = 30$

11)

$30 + 20 = x \\ 50 = x \\ x = 50$

12)

$4x + x + 20 = 90 \\ 5x = 90 - 20 \\ 5x = 70 \\ x = 14$
