Question

1.- Resuelve las siguientes ecuaciones (RECUERDA QUE ES EL USO DE LA LEY DE LOS SIGNOS)


PROCEDIMIENTO SOLUCION

46x = 90 + 45 + 5 – 2




2x – 124 = 430 + 22




5x – 72 = 243 + 5




x – 13.4 = 4.9 + 2.3




x + 3.8 = 5.2 – 3.4





5x = 243 + 72



10x = 350 + 10



x + 13.50 = 16.92



x+ 4 +2 = 7+ 5



x- 578 = 470





ayudaaaaaaaaaaaaaaaaaaaaa doy corona

Answer 1

Respuesta:

46x = 90 + 45 + 5 – 2

46x = 139

x = 139/46

2x – 124 = 430 + 22

2x = 430 + 22 + 124

2x = 556

x = 556/2

x = 278

5x – 72 = 243 + 5

5x = 243 + 5 + 72

5x = 320

x = 320/5

x = 64

x – 13.4 = 4.9 + 2.3

x = 4.9 + 2.3 + 13.4

x = 20.6

x + 3.8 = 5.2 – 3.4

x = 5.2 - 3.4 - 3.8

x = - 2

5x = 243 + 72

x = (243 + 72)/5

x = 315/5

x = 63

10x = 350 + 10

x = (350 + 10)/10

x = 36

x + 13.50 = 16.92

x = 16.92 - 13.50

x = 3.42

x+ 4 +2 = 7+ 5

x = 7 + 5 - 4 - 2

x = 6

x- 578 = 470

x = 470 + 578

x = 1048
