Langkah 1.1.1

Terapkan sifat distributif.

$3 x + 3 \cdot - 5 + 2 x = 5 (x + 5) - 40$

Langkah 1.1.2

Kalikan $3$ dengan $- 5$ .

$3 x - 15 + 2 x = 5 (x + 5) - 40$

Langkah 1.2

Tambahkan $3 x$ dan $2 x$ .

$5 x - 15 = 5 (x + 5) - 40$

Langkah 2

Sederhanakan $5 (x + 5) - 40$ .

Langkah 2.1.1

Terapkan sifat distributif.

$5 x - 15 = 5 x + 5 \cdot 5 - 40$

Langkah 2.1.2

Kalikan $5$ dengan $5$ .

$5 x - 15 = 5 x + 25 - 40$

Langkah 2.2

Kurangi $40$ dengan $25$ .

$5 x - 15 = 5 x - 15$

Langkah 3

Gambarkan setiap sisi persamaan. Penyelesaiannya adalah nilai x dari titik perpotongan.
