Maths class 8 0.5y+5y/6 =21 +0.75y

1.	Maths class 8 0.5y+5y/6 =21 +0.75y
Answer» $Given \: simple \: equation :\\0.5y + \frac{5y}{6} = 21 + 0.75y$ /* MULTIPLY each TERM by 6 , we get / $\implies 6 \times 0.5y + 6\times \frac{5y}{6} = 6 \times 21 + 6 \times 0.75y$ $\implies 3y + 5y = 126 + 4.5y$ $\implies 8y = 126 + 4.5y$ / SUBTRACT bothsides by 4.5y , we get / $\implies 8y - 4.5y = 126 + 4.5y - 4.5y$ $\implies 3.5y = 126$ / DIVIDE each term by 3.5, we get */ $\implies \frac{3.5y}{3.5} = \frac{126}{3.5}$ $\implies y = 36$ THEREFORE., $\red { Value \: of \: y } \green { = 36}$ •••♪
