plantear la ecuacion y resolver.​

Answer 1

Respuesta:

a) 49

b) 19

c) 74

d) 2

e) -5

Explicación paso a paso:

a)

2(x - 1) = 96

2x - 2 = 96

2x = 96 + 2

2x = 98

x = 98/2

x = 49

b)

4x - 1 = 75

4x = 75 + 1

4x = 76

x = 76/4

x = 19

c)

3(-x) = -222

-3x = -222

x = -222/-3

x = 74

d)

x - 1 = 2x - 3

x - 2x = -3 + 1

-x = -2

x = -2/-1

x = 2

e)

2x = 3x + 5

2x - 3x = 5

-x = 5

x = 5/-1

x = -5
