Question

resolva:

2(2x+7)+3(3x-5)=3(4x-5)-1

3(x+2)=2(x-7)

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

4(2m-1)+3m=2(4m-1)-(2-m)

3(x+3)-1=2​

3(x+2)-1=2(x+3)-7

me ajudem pfvv!​

Answer 1

Resposta:

1-x=-10

2-x=-20

3-x=2

4-m=0

5-x=-2

6-x=-6

Explicação passo-a-passo:

• 2(2x+7)+3(3x-5)=3(4x-5)-1

4x+14+9x-15=12x-20-1

14x-1=12x-21

14x-12x=-21+1

2x=-20

x=-20/2

x=-10

• 3(x+2)=2(x-7)

3x+6=2x-14

3x-2x=-14-6

x=-20

• 4(2x-1)=3(x+2)

8x-4=3x+6

8x-3x=6+4

5x=10

x=10/5

x=2

• 4(2m-1)+3m=2(4m-1)-(2-m)

8m-4+3m=8m-2-2+m

11m-4=9m-4

11m-9m=-4+4

2m=0

m=0

• 3(x+3)-1=2

3x+9-1=2

3x+8=2

3x=2-8

3x=-6

x=-6/3

x=-2

• 3(x+2)-1=2(x+3)-7

3x+6-1=2x+6-7

3x+5=2x-1

3x-2x=-1-5

x=-6
