Question

5/12y+1.3=0.53+7/8y решите плиз

Answer 1

5/12y+1.3=0.53+7/8y
5/12y-7/8y=0,53-1,3
-11/24y=-0,77
y=-0,77:(-11/24)
y=-77/100*(-24/11)
y=42/25
y=1 17/25

Answer 2

5/12y+1.3=0.53+7/8y 
5/12у+13/10=53/100+7/8у
5/12у-7/8у=53/100-13/10
у (5/12-7/8)=-77/100
у (10/24-21/24) = -77/100
у * (- 11/24) = - 77/100
11/24у = 77/100
у = 77/100 / 11/24 = 77/100 * 24/11 = 7 / 100 * 24 = 168/100
у = 1,68
