4y+3=\frac{3}{5}\times 2
Multiply both sides by 2.
4y+3=\frac{3\times 2}{5}
Express \frac{3}{5}\times 2 as a single fraction.
4y+3=\frac{6}{5}
Multiply 3 and 2 to get 6.
4y=\frac{6}{5}-3
Subtract 3 from both sides.
4y=\frac{6}{5}-\frac{15}{5}
Convert 3 to fraction \frac{15}{5}.
4y=\frac{6-15}{5}
Since \frac{6}{5} and \frac{15}{5} have the same denominator, subtract them by subtracting their numerators.
4y=-\frac{9}{5}
Subtract 15 from 6 to get -9.
y=\frac{-\frac{9}{5}}{4}
Divide both sides by 4.
y=\frac{-9}{5\times 4}
Express \frac{-\frac{9}{5}}{4} as a single fraction.
y=\frac{-9}{20}
Multiply 5 and 4 to get 20.
y=-\frac{9}{20}
Fraction \frac{-9}{20} can be rewritten as -\frac{9}{20} by extracting the negative sign.
