Question

resolva as equacoes

a)7X +2=6+2x

b) 3x-8=8-x

Answer 1

Explicação passo-a-passo:

a)

$7x + 2 = 6 + 2x$

$7x - 2x = 6 - 2$

$5x = 4$

$x = \frac{4}{5}$

b)

$3x - 8 = 8 - x$

$3x + x = 8 + 8$

$4x = 16$

$x = \frac{16}{4}$

$x = 4$

Answer 2

Explicação passo-a-passo:

7x+2=6+2x

7x-2x=6-2

5x=4

x=4/5

3x-8=8-x

3x+x=8+8

4x=16

x=16/4

x=4
