b) 2x-5=×+1
c) 4×-7=8×-2
d)2×+1=4×-7
e)9×+9+3×=15
f)16×-1=12×+3
g)3×-2=4×+9​​

Answer 1

Resposta:

a)x=16/3

b)x=6

c)x=-5/4

d)x=4

e)x=1/2

f)x=13/12

g)x=-11

Explicação passo-a-passo:

a)6x=2×+16

6x=32

x=16/3

b) 2x-5=×+1

2x-x=1+5

x=1+5

x=6

c) 4×-7=8×-2

4x-8x=-2+7

-4x=5

x=-5/4

d)2×+1=4×-7

2x-4x=-7-1

-2x=-8

x=4

e)9×+9+3×=15

12x+9=15

12x=15-9

12x=6

x=1/2

f)16×-1=12×+3

16=12x+3

-12x+16=3

-12x=-13

x=13/12

g)3×-2=4×+9​​

3x-2=4x+9

-x=9+2

-x=11

x=-11
