Answer 1

Jawaban:

1675

Penjelasan dengan langkah-langkah:

8x + 7 = 6x + 5

8x - 6x = 5 - 7

2x = -2

x = -1

x² + 6x - 7³ + 2023

= (-1)² + 6(-1) - 7³ + 2023

= 1 - 6 - 343 + 2023

= 1675

Answer 2

Verified answer

8x + 7 = 6x + 5

8x - 6x = 5 - 7

2x = -2

x = -2/2

x = -1

maka

x² + 6x - 7³ + 2.023

= (-1)² + 6(-1) - (7 × 7 × 7) + 2.023

= (-1 × -1) + -6 - (49 × 7) + 2.0223

= 1 + -6 - 343 + 2.023

= -5 - 343 + 2.023

= -348 + 2.023

= 1.675

koreksi
