Question

a)5x+7=4x+10 b)4x-10=2x+2 c)4x-7=8x-2 d)2x+1=4x-7 e) 9x+9+3x=15​

Answer 1

Resposta:

e só você dividir o resto pelo quociente

Answer 2

Resposta:

a) 5x+7=4x+10

5x+4x = 10 - 7

x = 3

B) 4X-10=2x+2

4x-2x=2+10

2x=12

x=12/2

x=6

c)4x-7=8x-2

4x-8x=-2+7

-4x=5

x=5/-4

d) 2X+1=4X-7

2X-4X=-7+1

-2x=-6

x= -2/-6

x=3

e)9x+9+3x=15

9x+3x=15-9

12x=6

x=6/12

x=0,5
