Answer:
[tex]y=\frac{15-3x}{4}[/tex]
Step-by-step explanation:
Here we are given an equation in x and y and we are required to solve it for y
we have
[tex]3x+4y=15[/tex]
subtracting 3x from each sides we get
[tex]3x-3x+4y=15-3x[/tex]
[tex]4y=15-3x[/tex]
now we divide both sides by 4 we get
[tex]\frac{4y{4}=\frac{15-3x}{4}[/tex]
[tex]y=\frac{15-3x}{4}[/tex]
Hence A) is our right answer.
