Question

C) 4 x - 8 = 6 + 2

D) 8x - 15 = 3x

E) 7x+1 = 5 x -7

Answer 1

C) 4 x - 8 = 6 + 2

4x-8=8

4x=8+8

4x=16

x=4

d) 8x - 15 = 3x

8x-3x=15

5x=15

x=3

e) 7x+1 = 5 x -7

7x-5x=-7-1

2x=-8

x= -4

Answer 2

Resposta:

4, 3 e -4

Explicação passo-a-passo:

c)

4x-8=6+2

4x=6+2+8

4x=16

x=16÷4

x=4

d)

8x-15=3x

8x-3x=15

5x=15

x=15÷5

x=3

e)

7x+1=5x-7

7x-5x= -7-1

2x= -8

x= -8÷2

x= -4
