Question

помогите решить уравнение

Answer 1

$\frac{5}{12} y + 1,3 = 0,53 + \frac{7}{8} y\\\\\frac{5}{12} y - \frac{7}{8} y = 0,53 - 1.3\\\\\frac{10}{24} y - \frac{21}{24} y = 0,53 - 1.3\\\\\frac{11}{24} y = \frac{77}{100} \\\\y = \frac{77*24}{11*100} \\\\y = \frac{42}{25} \\\\y = 1\frac{17}{25}$

Answer 2

5/12y+1.3=0.53+7/8y

5/12y+13/10=53/100+7/8y

250y+780=318+525y

250y-525y=318-780

-275y=-462

y=42/25(1 17/25;1.68)
