guys, yg bisa ngerjain tolong dong. pake cara terus difoto kirim ke saya yah.. butuh cepat nih.. gak ngerti bet sumpah

(1a) 2 (x+3) = 5(x-2) - 2
2x + 6 = 5x - 10 - 2
6 + 10 + 2 = 5x - 2x
18 = 3x
6 = x

(1b) 12x - (7x - 4) = 6 (x - 3) - 8x
12x - 7x + 4 = 6x - 18 - 8x
5x + 4 = -2x - 18
5x + 2x = -18 - 4
7x = 22
x = 22/7
