Math Problem Statement

Solve for x only

Complete the table for the given equation y = x + 5

Solution

The given equation is y=x+5y = x + 5, and we are solving for xx for each given yy.

We can rearrange the equation to solve for xx:

x=y5x = y - 5

Now, applying this formula to each yy-value in the table:

  • When y=4y = -4, x=45=9x = -4 - 5 = -9
  • When y=0y = 0, x=05=5x = 0 - 5 = -5
  • When y=4y = 4, x=45=1x = 4 - 5 = -1
  • When y=8y = 8, x=85=3x = 8 - 5 = 3
  • When y=12y = 12, x=125=7x = 12 - 5 = 7

Thus, the corresponding xx-values for the table are: x=9,5,1,3,7x = -9, -5, -1, 3, 7

Let me know if you'd like further details or have any questions!


Here are 5 related questions:

  1. What would the equation look like if we changed the constant from 5 to another number, say 3?
  2. How would the values of xx change if the equation were y=2x+5y = 2x + 5?
  3. What happens to the graph of this equation as the constant term increases or decreases?
  4. How would you complete the table if the equation was y=x+5y = -x + 5?
  5. Can you solve for yy if xx is given as 10?

Tip: Whenever you have a linear equation like y=x+5y = x + 5, rearranging it to solve for a variable can help you understand how changes in one variable affect the other.
