Answer:

a. y=\frac{2x}{x-5}

b. y=\frac{2-4x}{x-3}

Step-by-step explanation:

change switch x and y and then solve for y.

a. x=\frac{5y}{y-2}

x(y-2)=5y

xy-2x=5y

xy-5y=2x

y(x-5)=2x

y=\frac{2x}{x-5}

same for b.

b. x=\frac{3y+2}{y+4}

x(y+4)=3y+2

xy+4x=3y+2

xy-3y=2-4x

y(x-3)=2-4x

y=\frac{2-4x}{x-3}
