Question

35. Resolva as equações.
a) 6x = 2x + 16
b) 4x - 10 = 2x + 2
c) 2x + 1 = 4X-7​

Answer 1

resolução!

A )

6x = 2x + 16

6x - 2x = 16

4x = 16

X = 16/4

X = 4

B )

4x - 10 = 2x + 2

4x - 2x = 2 + 10

2x = 12

X = 12/2

X = 6

C )

2x + 1 = 4x - 7

2x - 4x = - 7 - 1

- 2x = - 8 * (-1)

X = 8/2

X = 4

Answer 2

Bom dia,

A)

6x = 2x + 16

4x = 16

x = 4

S = {4}

B)

4x - 10 = 2x + 2

2x = 12

x = 6

S = {6}

C)

2x + 1 = 4x - 7

2x = 8

x = 4

S = {4}

Abraços!
