Answer 1

Explicación paso a paso:

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

$4z - 14 = 2 \\ 4z = 2 + 14 \\ 4z = 16 \\ z = \frac{16}{4} \\ z = 4$

$3x + 8 = 35 \\ 3x = 35 - 8 \\ 3x = 27 \\ x = \frac{27}{3} \\ x = 9$

$4x - 20 = 4 \\ 4x = 4 + 20 \\ 4x = 24 \\ x = \frac{24}{4} \\ x = 6$

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

$x - 340 = 124 \\ x = 340 - 124 \\ x = 216$

$5y - 2 = 33 \\ 5y = 33 - 2 \\ 5y = 31 \\ y = \frac{31}{5} \\ y = 6.2$

$7x + 2 = 58 \\ 7x = 58 - 2 \\ 7x = 56 \\ x = \frac{56}{7} \\ x = 8$

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

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

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

$y - 43 = 50 \\ y = 50 - 43 \\ y = 7$

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

$2m - 18 = 2 \\ 2m = 2 + 18 \\ 2m = 20 \\ m = \frac{20}{2} = > 10$

$\frac{x}{6} + 2 = 4 \\ \frac{x}{6} = 4 + 2 \\ \frac{x}{6} = 6 \\ x = 6 \times 6 \\ x = 36$

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

espero te sirva
