Answer 2

Explicación paso a paso:

A1.

$3a - a = 18 - 4 \\ a = 14$

A3.

$2c - 3c + 12 = c + 2 \\ 2c - 3c - c = 2 - 12 \\ - 2c = - 10 \\ 2c = 10 \\ c = \frac{10}{2} \\ c = 5$

A9.

$1 + 4x = 5 \\ 4x = 5 - 1 \\ 4x = 4 \\ x = \frac{4}{4} \\ x = 1$

B7.

$- 2s = - 11 + 5 \\ - 2s = - 6 \\ 2s = 6 \\ s = \frac{6}{2} \\ s = 3$

D3.

$- 2x + 3x = - 5 + 13 \\ x = 8$

D8.

$4y - 6y = - 5 - 9 \\ - 2y = - 14 \\ 2y = 14 \\ y = \frac{14}{2} \\ y = 7$

E6.

$\frac{3}{4} t = \frac{31}{6} - \frac{2}{3} \\ \frac{3}{4} t = \frac{27}{6} \\ 18t = 486 \\ t = \frac{486}{18} \\ t = 27$

E9.

$- 9 + 14 = p \\ 5 = p$

F7.

$\frac{4}{6} = \frac{m}{9} \\ 36 = 6m \\ \frac{36}{6} = m \\ 6 = m$

G1.

$- 4x - 24 = - 40 \\ - 4x = - 40 + 24 \\ - 4x = - 16 \\ 4x = 16 \\ x = \frac{16}{4} \\ x = 4$

G4.

$8y - 2y + 3 = 9 \\ 6y = 9 - 3 \\ 6y = 6 \\ y = \frac{6}{6} \\ y = 1$

I2.

$3d - d - 4 = - 2 \\ 2d = - 2 + 4 \\ 2d = 2 \\ d = \frac{2}{2} \\ d = 1$

I8.

$3x = 16 + 2 \\ 3x = 18 \\ x = \frac{18}{3} \\ x = 6$

A2.

$6 - 6p + 12 = - 18 \\ 6p = - 18 - 12 - 6 \\ 6p = 0 \\ p = 0$

A6.

$0.5t - 3t + 5 = 0 \\ - 2.5t = - 5 \\ 2.5t = 5 \\ t = \frac{5}{2.5} \\ t = 2$

B6.

$1 - 6y + - 18 = - 23 \\ 1 - 18 + 23 = 6y \\ 6 = 6y \\ \frac{6}{6} = y \\ 1 = y$

C1.

$4u + 2u = 5 + 7 \\ 6u = 12 \\ u = \frac{12}{6} \\ u = 2$

D5.

$5z - 2z = 5 - 2 \\ 3z = 3 \\ z = \frac{3}{3} \\ z = 1$

E1.

$2s = 18 \\ s = \frac{18}{2} \\ s = 9$

E8.

$7x - x= 10 + 2 \\ 6x = 12 \\ x = \frac{12}{6} \\ x = 2$

F4.

$2a + 4 = 3a - 3 \\ 2a - 3a = - 3 - 4 \\ - a = - 7 \\ a = 7$

F8.

$2b - 6b = - 32 - 4 \\ - 4b = - 36 \\ 4b = 36 \\ b = \frac{36}{4} \\ b = 9$

G3.

$2x + x = 20 + 7 \\ 3x = 27 \\ x = \frac{27}{3} \\ x = 9$

H4.

$16 + 2p = 22 \\ 2p = 22 - 16 \\ 2p = 6 \\ p = \frac{6}{2} \\ p = 3$

I6.

$5c - 2c = 12 + 3 \\ 3c = 15 \\ c = \frac{15}{3} \\ c = 5$

Todos resueltos y ordenados.
