Question

48+2(x+6)=80

3x/4+8=23

3(x+9)-15=36

4(2x+18-65=5x+37

2x/5-13=7

Porfa resolver los 6

Answer 1

Respuesta:

1) x = 10

2) x = 20

3) x = 8

4) x = 10

5) x = 50

Explicación paso a paso:

1) 48 + 2(x + 6) = 80

2x + 12 = 80 - 48

2x = 32 - 12

x = 20/2

x = 10

2)

3x/4 + 8 = 23

3x + 32 = 92

3x = 92 - 32

x = 60/3

x = 20

3)

3(x + 9) - 15 = 36

3x + 27 = 36 + 15

3x = 51 - 27

x = 24/3

x = 8

4)

4(2x + 18) - 65 = 5x + 37

8x + 72 = 5x + 37 + 65

8x - 5x = 102 - 72

3x = 30

x = 30/3

x = 10

5)

2x/5 - 13 = 7

2x/5 = 7 + 13

2x = 20(5)

x = 100/2

x = 50
