Question

Решите уравнение для 6 класса 5-(1 1/2у + 1/3)*6=2 1/3у-5 1/2

Answer 1

5-(3/2у+1/3)*6=2 1/3у-5 1/2
5-9у-2=2 1/3у-5 1/2
3-9у=2 1/3у-5 1/2
-9у-2 1/3у= -5 1/2-3
-11 1/3у= -8 1/2
у= -8 1/2:(-11 1/3)
у= - 17/2:(-34/3)
у= -17/2*(-3/34)
у= 3/4

Answer 2

$5-(1 \frac{1}{2}y+ \frac{1}{3})*6=2 \frac{1}{3}y-5 \frac{1}{2} \\ 5-( \frac{3}{2}y+ \frac{1}{3})*6= \frac{7}{3}y- \frac{11}{2} \\ 5- \frac{18}{2}y- \frac{6}{3} = \frac{7}{3}y- \frac{11}{2} \\ - \frac{18}{2}y- \frac{7}{3}y=- \frac{11}{2}+2-5 \\ - \frac{20}{3}y=- \frac{17}{2} \\ y=- \frac{17}{2}*(- \frac{3}{20} \\ y= \frac{51}{60}$
