Question

g. 3x - 5 = 16 h. 25 - 15 = 4x - 10
i. 5x + 5 = 3x + 25 j. 6x - 10 = 2x + 18
k. 7x + 6 + 5 = 13x - 1

Answer 1

Explicación paso a paso:

g. 3x - 5 = 16

3x = 16 + 5

3x = 21

x = 7

h. 25 - 15 = 4x - 10

10 = 4x - 10

10 + 10 = 4x

20 = 4x

5 = x

i. 5x + 5 = 3x + 25

5x - 3x = 25 - 5

2x = 20

x = 10

j. 6x - 10 = 2x + 18

6x - 2x = 18 + 10

4x = 28

x = 7

k. 7x + 6 + 5 = 13x - 1

7x + 11 = 13x - 1

11 + 1 = 13x - 7x

12 = 6x

2 = x
