Question

Resuelve la siguiente lista de ecuaciones:
• 7m - 9 = 2
• - 2y + 3 = -1
• 15 n + 3 20
• 5 - 6 t = 8
• - 1 - 20 x = 40
• 4x + 5 = 3x - 10
• - 12 + 3m = 8m – 6

Answer 1

Explicación paso a paso:

7m = 2+9...7m = 11....m = 11/7

-2y = - 1 - 3...-2y = - 4...y = 2

15n = 20 - 3...15n = 17...n = 17/15

5 - 8 = 6t....-3 = 6t...t = - 3/6...t = - 1/2

-1 - 40 = 20x...-41 = 20x...x = - 41/20

4x - 3x = - 10 - 5...x = - 15

-12 + 6 = 8m - 3m....-6 = 5m....m = - 6/5
