Question

Resolver las siguientes ecuaciones: A- 3 . a + 10 = 40. B- 8 . x - 15 = 65 C- 4 . y + 3. y = 14 + 3 . 7 D- 6 . t + 15 = 2 . t + 13 Ayuda!!!!!!!!!!!!!!

Answer 1

3 . a + 10 = 40

3a = 40 - 10

3a = 30

a = 30/3

a = 10

8 . x - 15 = 65

8x = 65 + 15

8x = 80

x = 80/8

x = 10

4 . y + 3. y = 14 + 3 . 7

7y = 14 + 21

7y = 35

y = 35/7

y = 5

6 . t + 15 = 2 . t + 13

6t - 2t = 13 - 15

2t = -2

t = -2/2

t = -1
