Tolong kak!! Please tolong Saya. Mudah kok soalnya

Penjelasan dengan langkah-langkah:

(gambar 1)

7x + 4 = 5x – 2

7x – 5x = – 2 – 4

2x = -6

x = -6/2

x = -3

(gambar 2)

$frac{3x - 5}{4} - frac{2x + 3}{3} = 13 \12(frac{3x - 5}{4} - frac{2x + 3}{3} = 13 )\ 3(3x - 5) - 4(2x + 3) = 156 \ 9x - 15 - 8x - 12 = 156 \ 9x - 8x - 15 - 12 = 156 \ x - 27 = 156 \ x = 156 + 27 \ x = 183$
