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
