We just use the techniques in algebra. Isolate the terms that are not x on the right side, while only the x variable on the left side. To do this, divide both sides by b. The b on the left side would then cancel out. As a result, the equation for x is written below:

x = -7/b

Answer:

$x=-\frac{7}{b}$

Step-by-step explanation:

We have been given an equation $bx=-7$ , where b represents a nonzero constant. We are asked to solve for x.

We will use opposite operations to solve our given problem.

Since b represents a nonzero constant, so we can divide both sides of our equation by b as:

$\frac{bx}{b}=\frac{-7}{b}$

$x=-\frac{7}{b}$

Therefore, the solution of our given equation would be $x=-\frac{7}{b}$ .

Ken normally leaves work at 5:00 pm, but he is leaving 20 minutes late today. He decides to make up time by taking the toll road

Answer:

The correct answer is: $y=\frac{1}{3} x + 20$

Step-by-step explanation:

As stated in the question that x represents the number of minutes his normal commute takes. Here the keyword is normal; in the normal commute, Ken takes side streets instead of the toll road.

However, in this scenario, we have to come up with the equation that takes Ken's commute via toll road.

Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:

$x_{toll\_road}=\frac{1}{3}x$
