Answer:

  • 3. x = - 2,
  • 4. x = 1

-----------------------------

Question 3

Given equation:

  • x + 4 = - x

In order to solve it by graphing, plot two lines:

  • y = x + 4 and
  • y = - x

The solution is the x-coordinate of the intersection of the lines:

  • x = - 2

See the attached

Question 4

Given equation:

  • -2x + 6 = 5x - 1

Similar to the previous question, plot the lines and take the x-coordinate of the intersection as solution.

  • y = - 2x + 6 and
  • y = 5x - 1

The solution is x = 1.

See the attached.
