A.) 6x - 3y ÷ 3 = 6x - y
B.) y/2 + x-3/3y
= y(3y)/2(3y) + x-3(2)/3y(2)
= 3y² + 2x- 6/6y
= y + 2x - 3
= 2x + y - 3
C.) 2/x+2 - 3/x+3
= 2(x+3)/(x+2)(x+3) - 3(x+2)/(x+3)(x+2)
= 2x +6 - 3x + 2/x²+5x+6
= 2x-3x+6+2/x²+5x+6
= -x + 8/x²+5x+6
D.) 3x/2 × x-4/6x
= 3x × 6x = x-4(2)
18x² = 2x-8
18 x²/2x = -8
9x = -8
E.) 3ab/2c ÷ 9b²/4ac
= 3ab/2c × 4ac/9b²
= 2a²/3
F.) 18 a³b^5c^4 ÷ 6 ab²c
= 3 a²b³c³
maaf jika jawaban saya
semoga bermanfaat
