How do you do this solve 5/2y=10 for y explain

Sagot :

5/2Y pretty much = 2 1/2 y = 10 So all you do is divide both sides by 2 1/2 Which leaves Y = 4 Also you can say if you still don't understand it, what times itself 2 times and plus half itself = 10 you can say 4 Ex: 4 + 4 + (1/2 of 4=2) 10 so it's 4
[tex]if\ \frac{5}{2}y=10\ \ \ \ \ |divide\ both\ sides\ by\ \frac{5}{2}\ (multiply\ by\ \frac{2}{5})\\\\y=\frac{\not10^2}{1}\cdot\frac{2}{\not5_1}\\\\\boxed{y=4}\\===============================\\if\ \frac{5}{2y}=10\\\\\frac{5}{2y}=\frac{10}{1}\ \ \ \ |cross\ multiply\\\\2y\cdot10=5\cdot1\\\\20y=5\ \ \ \ \ |divide\ both\ sides\ by\ 20\\\\y=\frac{5}{20}\\\\\boxed{y=\frac{1}{4}}[/tex]
