me ajuda pvf ​

Answer 1

Explicação passo-a-passo:

a) 5x+8=-3+4

5x=-3+4-8

5x=-7

x=7/2

b) 2x-1=10-4x

2x+4x=10+1

6x=11

x=11/6

c)6+2x=8x+1

2x-8x=1-6

-6x=-5 ×(-1)

6x=5

x=5/6

d)2x-18=5x+3

2x-5x=3+18

-3x=21 ×(-1)

3x=21

x=21/3

x=7

e) 50+3x=-10-2x

3x+2x=-10-50

5x=-60

x=-60/5

x=-12

f)2x+16=8

2x=8-16

2x=-8

x=-8/2

x=-4
