Solve the equation $7 x + 3 y - 9 = 0$ for $y$ .
A) $y = \frac { 9 - 7 x } { 3 }$ or $y = 3 - 2.33 x$

B) $y = \frac { 9 + 7 x } { 3 }$ or $y = 3 + 2.33 x$

C) $y = \frac { 7 x - 9 } { 3 }$ or $y = 2.33 x - 7$

D) None of the above.

Quizplus · Accepted Answer

To solve for $y$, isolate $y$ on one side of the equation: $7x + 3y - 9 = 0$ becomes $3y = 9 - 7x$, and then $y = \frac{9 - 7x}{3}$, which simplifies to $y = 3 - \frac{7}{3}x$ or $y = 3 - 2.33x$.

Solve the Equation 7x+3y−9=07 x + 3 y - 9 = 07x+3y−9=0

Solve the Equation $7 x + 3 y - 9 = 0$
