Question

a) 2x + 5 - 5x = -1

b) 5 + 6x = 5x + 2

c) x + 2x - 1 - 3 = x

d) -3x + 10 = 2x + 8 +1

e) 5x - 5 + x = 9 + x

Podem me ajudar por favor TwT!!!

Answer 1

a) 2x + 5 - 5x = -1

2x - 5x = -1 - 5

-3x = -6

x = -6/-3

x = 2

b) 5 + 6x = 5x + 2

6x - 5x = 2 - 5

x = -3

c) x + 2x - 1 - 3 = x

3x - x = 1 + 3

2x = 4

x = 4/2

x = 2

d) -3x + 10 = 2x + 8 +1

-3x - 2x = 8 + 1 - 10

-5x = 9 - 10

-5x = -1

x = -1/-5

x = 1/5

e) 5x - 5 + x = 9 + x

6x - x = 9 + 5

5x = 14

x = 14/5
