Question

Calcule:

1- 3p+5=254

2- x-x/5 = 36

3- 4x-8=10

4- 7x-2=4x+5

Answer 1

Resposta:

1) p= 83

2) x= 45

3)x= 9/2

4)x= 7/3

Explicação passo-a-passo:

Resolução :

1)

3p +5 = 254

3p = 254 - 5

3p= 249

p = 249/3

p= 83

2)

x - x/5 = 36

5x - x = 180

4x = 180

x =180/4

x= 45

3)

4x - 8 = 10

4x = 10+8

4x = 18

x= 18:2/4:2

x= 9/2

4)

7x - 2 = 4x +5

7x - 4x = 5+2

3x = 7

x= 7/3
