Respuesta:

x⇒incógnita

3x+20⇒1° miembro

50⇒2° miembro

$x + 23 = 32 \\ x = 32 - 23 \\ x = 9$

$m - 48 = 12 \\ m = 12 + 48 \\ m = 60$

$3x + 8 = 35 \\ 3x = 35 - 8 \\ 3x = 27 \\ x = 9$

$\frac{x}{2} = 10 \\ 2 \times \frac{x}{2} = 2 \times 10 \\ x = 20$

$\frac{x}{3} + 5 = 20 \\ \frac{x}{3} = 20 - 5 \\ \frac{x}{3} = 15 \\ 3 \times \frac{x}{3} = 3 \times 15 \\ 45$

$y - 43 = 50\\ y = 50 + 43 \\ y = 93$

$m + 14 = 33 \\ m = 33 - 14 \\ m = 19$

$2m - 18 = 2 \\ 2m = 2 + 18 \\ 2m = 20 \\ m = 10$

$4z - 14 = 2 \\ 4z = 2 + 14 \\ 4z = 16 \\ z = 4$

$4x - 20 = 4 \\4 x = 4 + 20 \\ 4x = 24 \\ x = 6$

$z + 147 = 251 \\ z = 251 - 147 \\ z = 104$

$x - 340 = 124 \\ x = 124 + 340 \\ x = 464$

$5y - 2 = 33 \\ 5y = 33 + 2 \\ 5y = 35 \\ y = 7$

$7x + 2 = 58 \\ 7x = 58 - 2 \\ 7x = 56 \\ x = 8$

$\frac{x}{7} = 8 \\7 \times \frac{x}{7} = 7 \times 8 \\ x = 56$

$\frac{x}{6} + 2 = 4 \\ \frac{x}{6} = 4 - 2 \\ \frac{x}{6 } = 2 \\ 6 \times \frac{x}{6} = 6 \times 2 \\ x = 12$

$\frac{x}{6} = 5 \\ 6 \times \frac{x}{6} = 6 \times 5 \\ x = 30$
