Solve the equation for y.<br><br> 6y+x=8
iVinArrow [24]

Answer:

The correct answer is \bold{y = -\frac{1}{6}x+\frac{4}{3}}.

Step-by-step explanation:

We want to solve for y in the given equation. We can do this by rearranging the equation and using operational techniques to simplify.

6y + x = 8 \ $\tex Subtract x from both sides of the equation.

6y + x - x = 8 - x \ $\tex Carry out the operation.

6y = 8 - x \ $\tex Rearrange so the equation lists the variables first and the constants second.

6y = -x + 8 \ $\tex Create a coefficient for the x-variable (this is -1).

6y = -1x + 8 \ $\tex Divide by 6 on both sides of the equation in order to isolate the y-variable.

\frac{6y}{6}=\frac{-1x}{6} + \frac{8}{6} \ $\tex Carry out this operation by simplifying the fractions and dividing out the operations accordingly.

y = -\frac{1}{6}x+\frac{4}{3} \ $\tex Be sure to verify that all fractions and terms are simplified as far as they can be and that the equation is written in proper syntax.

Because we have the <em>y</em>-variable isolated from the rest of the equation, we are done!
