Alguem me ajuda a resolver essas equaçoes eu ja fiz mais quero saber se esta certo

Answer 1

2x-1=-3+x+4
2x-x=-3+4+1
x=8

3x-2-2x-3=0
3x-2x=3+2
x=5

10-9x+2x=2-3x
-9x+2x+3x=2-10
(-4x=-8) × (-1)
x=8÷4
x=2

4x-4-5x=-6+90
4x-5x=-6+90+4
(-x=88) × (-1)
x=-88

2-3x=-2x+12-3x
-3x+2x+3x=12-2
2x=10
x=10÷2
x=5

Answer 2

Bom dia,

a) 2x-1=-3+x+4

2x-x=-3+4+1

x=2

b)3x-2-2x-3=0

3x-2x=3+2

x=5

c)10-9x+2x=2-3x

-9x+2x+3x=2-10

-4x=-8 (×-1)

4x=8

x=8/4

x=2

d)4x-4-5x=-6+90

4x-5x=90-6+4

-x=88 (×-1)

x=88

e)2-3x=-2x+12-3x

-3x+2x+3x=12-2

2x=10

x=10/2

x=5

Espero ter ajudado =)
