Question

Alguem me ajuda o mais rapido possivel
Resolva as equações:

a)4x + 10 = x – 5

b)5x – 4 + 2x = 10

c)6x – 24 = 0

d)2x – 10 = x + 8

e)4x – 5 = 15

f)2x + 12 = 20

g)5x = 30

Answer 1

a)4x + 10=x-5

4x + x=—5-10

5x=—15

X= 15/5




B)5x —4 + 2x=10

5x+2x=10 + 4

7x=14

X=14/7

X=2




C)6x — 24=0

6x=24

X=24/6

X=4

D)2x — 10 = x +8

2x — x=8+10

X=18

E)4x —5 =15

4x=15 +5

X=20/4

X=4


F)2x +12=20

2x=20-12

2x=8

X=8/2

X=4



G) 5x=30

5x=30

X=30/5

X=6
