Quiz2x + 3 = 3x + 5maka, x = …​

Jawaban:

2x + 3 = 3x + 5

maka , x = …

penyelesaian :

2x + 3 = 3x + 5

2x – 3x = 5 – 3

-1x = 2

x = -2

2(-2) + 3 = 3(-2) + 5

(-4) + 3 = (-6) + 5

-1 = -1

jadi nilai x = –2

Jawaban:

x = -2

Penjelasan dengan langkah-langkah:

2x + 3x = 3x + 5

→2x – 3x = 5 – 3

→2x – 3x = 5 – 3

→ -1x = 2

→ x = -1 × 2

→ x = -2

______________

2(-2) + 3 = 3(-2) + 5

→ -4 + 3 = -6 + 5

→ -(4-3) = -(6-5)

→ -1 = -1
