Enter the value of y that makes the given equatlon true.<br> 15y +3= 6
Lunna [17]

Answer:

y = 1/5 or y = 0.2

Step-by-step explanation:

15y +3= 6\\15y+3-3=6-3\leftarrow \text {Subtraction Property of Equality} \\15y=3\\\\\frac{15y}{15} =\frac{3}{15} \leftarrow \text {Divsion Property of Equality}\\

y=\frac{3}{15}\\\frac{3/3}{15/3} = \frac{1}{5} \leftarrow \text {Simplifying the Answer}\\\boxed{y=\frac{1}{5}}
