Question

Ecuaciones de 6 - 2 h + 2 = 10

5 - 5 m + 10 = 30

6 - 3 n - 6 = 12

2 + 5 - d = 20

12 - t + 4 = 6

Ayuden porfavor es para mañana si eres Universitario mejor

Answer 1

1)

$6 - 2h + 2 = 10 \\ - 2h = 10 - 6 - 2 \\ - 2h = 10 - 8 \\ - 2h = + 2 \\ h = + 2 \div ( - 2) \\h = - 1 \\ \\ \\ verificacion \\ 6 - 2 \times ( - 1) + 2 = 10 \\ 6 + 2 + 2 = 10 \\ 10 = 10$

2)
$5 - 5m + 10 = 30 \\ - 5m = 30 - 5 - 10 \\ - 5m = 30 - 15 \\ - 5m = 15 \\ m = 15 \div ( - 5) \\ m = - 3 \\ \\ \\ verificacion \\ \\ 5 - 5 \times ( - 3) + 10 = 30 \\ 5 + 15 + 10 = 30 \\ 30 = 30$


3)

$6- 3n - 6 = 12 \\ - 3n = 12 + 6 - 6 \\ - 3n = 12 \\ n = 12 \div ( - 3) \\ n = - 4 \\ \\ \\ verificacion \\ \\ 6 - 3 \times ( - 4) - 6 = 12 \\ 6 + 12 - 6 = 12 \\ 12 = 12$

4)

$2 + 5 - d = 20 \\ - d = 20 - 2 - 5 \\ - d = 20 - 7 \\ - d = 13 \\ d = 13 \div( - 1) \\ d = - 13 \\ \\ \\ verificacion \\ \\ 2 + 5 - ( - 13) = 20 \\ 2 + 5 + 13 = 20 \\ 20 = 20$

5)

$12 - t + 4 = 6 \\ - t = 6 - 12 - 4 \\ - t = 6 - 16 \\ - t = - 10 \\ t = - 10 \div ( - 1) \\ t = + 10 \\ \\ \\ verificacion \\ \\ 12 - ( + 10) + 4 = 6 \\ 12 - 10 + 4 = 6 \\ 16 - 10 = 6 \\ 6 = 6$



espero haberte ayudado
