Answer:
Explanation:
The first step in solving the equation for y is to subtract 7x from both sides. This gives
[tex]7x+4y-7x=16-7x[/tex][tex]\Rightarrow4y=16-7x[/tex]finally, dividing both sides by 4 gives
[tex]\frac{4y}{4}=\frac{16-7x}{4}[/tex][tex]y=\frac{16-7x}{4}[/tex]rewriting the right-hand side gives
[tex]y=\frac{16}{4}-\frac{7}{4}x[/tex][tex]\Rightarrow\boxed{y=4-\frac{7}{4}x}[/tex]which is our answer!
