Question

Resolva as equações:

x-3-x+2+2x-1-5=0

3x-24x-3=2-3x-1

3x-1-x-3+5x-2=18

5x-3-4x+2=2+31-2x ​

Answer 1

Explicação passo-a-passo:

Answer 2

Resposta:

1)

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

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

2x-5-7=0

2x=7+5

2x=12

x=12/2

x=6

2)

3x-2(4x-3)=2-3(x-1)

3x-8x+6=2-3x+3

3x-8x+3x=2+3-6

-2x= -1

   x= -1/-2

   x= 1/2

3)

3(x-1)-(x-3)+5(x-2)=18

3x-3-x+3+5x-10=18

3x-x+5x=10+18

7x=28

x=28/7

x=4

4)

5(x-3)-4(x+2)=2+3(1-2x)

5x-15-4x-8=2+3-6x

5x-4x+6x=5+8+15

7x=28

x=28/7

x=4
