Answer 1

Explicação passo a passo:

a) 6x=2x+16

6x-2x=16

4x=16

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

x= 4

b) 2x-5=x+1

2x-x=1+5

x=6

c) 2x+3=x+4

2x-x=4-3

x=1

d) 5x+7=4x+10

5x-4x=10-7

x=3

e) 4x-10=2x+2

4x-2x=2+10

2x=12

$x=\frac{12}{2}$

x=6

f)4x-7=8x-2

-7+2=8x-4x

4x=-5

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

x= -1,25

g)2x+1=4x-7

4x-2x=1+7

2x=8

$x=\frac{8}{2}$

x=4

h)9x+9+3x=15

12x=15-9

12x=6

$x=\frac{6}{12}$

x=0,5

i)16x-1=12x+3

16x-12x=3+1

4x=4

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

x=1

j)3x-2=4x+9

-2-9=4x-3x

x=-11
