Answer:

C. y = 5 - 3x/4

Explanation:

3x + 4y = 5

Subtract 3x from both sides.

4y = 5−3x

Divide both sides by 4.

4y/4 = 5 - 3x/4

Dividing by 4 undoes the multiplication by 4.

y = 5 - 3x/4

Answer:


\textsf{(c)}\quad y=(5-3x)/(4)

Explanation:

To make y the subject of the equation 3x + 4y = 5, use algebraic operations to rearrange the equation and isolate y.

Begin by subtracting 3x from both sides of the equation:


\begin{aligned}3x+4y-3x&=5-3x\\\\4y&=5-3x\end{aligned}

Now, divide both sides of the equation by 4:


\begin{aligned}(4y)/(4)&=(5-3x)/(4)\\\\y&=(5-3x)/(4)\end{aligned}

Therefore, the equation is:


\Large\boxed{\boxed{y=(5-3x)/(4)}}
