Question

resolva as equações do primeiro grau 5×-12=3
3×-8=×+4
5 (×-1)=3 (2×+1)
2. (×+3)=×-18
50+(3×-4)=2. (3×-4)+26
Me ajudem pfvv​

Answer 1

Resposta:

5x-12=3

5x=3+12

5x=15

x=15/5

x=3

3x-8=x+4

3x-x= 4 +8

2x=12

x=12/2

x=6

5(x-1)=3(2x+1)

5x-5=6x+3

5x - 6x = 3 +5

-1× = 8

x=-8

2(x+3)=x-18

2x +6=x-18

2x-x = -18-6

x= - 24

50+(3x - 4)= 2(3x -4)+26

50+3x -4= 6x - 4 +26

3x - 6x = -4 +26 +4 -50

-3x = - 24

x= 24/3

x= 8

Answer 2

Resposta:

5x-12=3

5x=3+12

5x=15

x=15/5

x=3

3x-8=x+4

3x-x=4+8

2x=12

x=12/2

x=6

5 (×-1)=3 (2×+1)

5x-5=6x+3

5x-6x=3+5

-1x=8 (-1)

x= -8

2. (×+3)=×-18

2x+6=x-18

2x-x=-18-6

x=-24
