Question

01. Resolva a equação 5x - 5 = 2x + 4.
02. Resolva a equação 2x + 5 = 4x + 3.​

Answer 1

Resposta:

1.5x-5 = 2x + 4

5x-2x=4+5

3x=9

X=9/3

x=3

2.2x+5=4x+3

2x-4x=3-5

-2x=-2 .(-1)

2x=2

x=2/2. x=1

Answer 2

01)

5x - 5 = 2x + 4

5x - 2x = 4 + 5

3x = 9

x = 9/3

x = 3

02)

2x + 5 = 4x + 3

2x - 4x = 3 - 5

- 2x = - 2 . (-1)

2x = 2

x = 2/2

x = 1
