question 3
solve the equation for y.
x = 7y + 4
a y=x - \frac{4}{7}
b y=\frac{1}{7}x - \frac{4}{7}
c y=\frac{1}{7}x - 4
d y = 7x - 4

Explanation:

Step1: Isolate the term with y

Subtract 4 from both sides of the equation $x = 7y+4$, we get $x - 4=7y$.

Step2: Solve for y

Divide both sides of the equation $x - 4 = 7y$ by 7. So $y=\frac{1}{7}x-\frac{4}{7}$.

Answer:

B. $y=\frac{1}{7}x - \frac{4}{7}$
