Answer 1

Respuesta:

2a + 6 = 2

2a = 4

a = 2

b) 8m – 6 = 10

8m = 16

m = 2

c) 2x + 14 = 8

2x = -6

x = -3

d) 5y + 3 = 8

5y = 5

y = 1

e) 4x + 2 = 10

4x = 8

x = 2

f)5y + 3 = 8

5y = 5

y = 1

g)2y + 14 = 8

2y = -6

y = -3

h)2a + 7 = 33

2a = 26

a = 13

i)4x + 8 = 36

4x = 24

x = 6

j)3x + 18 = 30

3x = 12

x = 4

Explicación paso a paso:

3x + 6 = 12

3x = 12 - 6

3x = 6

x = 6/3

x = 2
