Question

resolva as equações:

5x-x=16

4x-x+2x-3=12

6x-2x=20

5x=10+X

6x-2=8+X

Answer 1

Explicação passo-a-passo:

5x-x=16

4x = 16

x = 16/4

x = 4

4x-x+2x-3=12

5x = 12 + 3

5x = 15

x = 15/5

x = 3

6x-2x=20

4x = 20

x = 20/4

x = 5

5x=10+X

5x - x = 10

4x = 10

x = 10/4

x = 2,5

6x-2=8+X

6x - x = 8 + 2

5x = 10

x = 10/5

x = 2
