Answer 2

$\frac{15}{12}y+1.3=0.53+\frac{7}{8}y$

$\frac{5y}{4}+1.3=\frac{7y}{8}+0.53$

$\frac{5y}{4}+\frac{5.2}{4}=\frac{7y}{8}+0.53$

$\frac{5y+5.2}{4}=\frac{7y}{8}+0.53$

$\frac{5y+5.2 }{4}=\frac{7y}{8}+\frac{4.24}{8}$

$\frac{5y+5.2}{4}=\frac{7y+4.24}{8}$

$\frac{8(5y+5.2}{4}=\frac{8(7y+4.24)}{8}$

$2(5y+5.2)=7y+4.24$

$10y+10.4=7y+4.24$

$3y=-6.16$

$y=-2.05333$
