Jawaban Terkonfirmasi

9/4 – 2/3 = -1 + y – 4y
19/12 + 1 = -3y
31/12 = -3y
y = 31/12 x (-1/3)
y = – 31/36

Jawaban Terkonfirmasi

$begin{align} frac{9}{4}+1-y&=2(frac{1}{3}-2y)\frac{13}{4}-y&=frac{2}{3}-4y\3y&=frac{8-39}{12}\3y&=-frac{31}{12}\y&=-frac{31}{12}timesfrac{1}{3}\y&=-frac{31}{36} end{align}
