6) Determine a raiz de cada equação.
a) 8 . (x – 5) – x = 51
b)6x – 12 = – 4x

Answer 1

Resposta:

a)13/b)1,2

Explicação passo-a-passo:

a)8x-40-x=51

8x-x=51+40

7x=91

x=13

b)6x-12=-4x

6x+4x=12

10x=12

x=1,2

Answer 2

A) X+5=11

X=11-5

X=6

b)x + 10 = 7

X=7-10

X= -3

c)x + 6 = -5

X=-5-6

X=-11

d)x - 8 = -10

X=-10+8

X=-2

e)6x = 42

X=42÷6

X=7

f)-3x = 24

X=24÷3

X=8

g)x3= -12

x=-12÷3

x=-4

h)5x - 4 = 21

5x=21-4

5x=25

x=25÷5

x=5
