B I Write an equation with a variable on both sides of the equal sign that has no solution. Solve the equation and explain why it has no solution. (3 points) Ξ Σ 0 / 10000 Word Limit

Answer 1

Let's start with the inequality for Brian's earnings to buy the new cell phone:

8.00h ≥ 320.00

To solve for h, we need to divide both sides by 8:
h ≥ 40

So, Brian needs to work at least 40 hours on the weekends to buy the new cell phone.

Now, let's create an equation with a variable on both sides of the equal sign that has no solution:
2x + 5 = 2x + 10

Subtract 2x from both sides:
5 = 10

However, 5 does not equal 10. So, there is no solution to this equation.
