Question

1) Calcular el valor de x

a_ 4× + 40 = 100

b_ 15× + 40 = 70

c_ 5× - 5 = 45 - 5×

d_6x - 10 = 50 - 4x

e_ 9× - 63 = 3^(2) (tres al cuadrado)

​

Answer 1

Respuesta:

a) 4x + 40 = 100

x = (100-40)/4

b) 15x + 40 = 70

x = (70-40)/15

c) 5x - 5 = 45 - 5x

5x + 5x = 45 + 5

10x = 50

x = 50/10

d) 6x - 10 = 50 - 4x

6x + 4x = 50 + 10

10x = 60

x = 60/10

e) 9x - 63 = 3²

x = (3²+ 64)/9

Solo resuelves la x.
