Step-by-step explanation:

Step 1: Define

Identify

y = -23(x + 9) + 4

y = 0

Step 2: Solve for x

  1. Substitute in y:                                                                                                  0 = -23(x + 9) + 4
  2. [Subtraction Property of Equality] Subtract 4 on both sides:                        -4 = -23(x + 9)
  3. [Division Property of Equality] Divide -23 on both sides:                                4/23 = x + 9
  4. [Subtraction Property of Equality] Subtract 9 on both sides:                        -203/23 = x
  5. Rewrite:                                                                                                             x = -203/23

Answer:

-203

Step-by-step explanation:

remove the 0 ( when adding or substracting 0, the quantity does not change

y=-23 (9+4)

Multiply the numbers -23x9

y= =207+4

Calculate the sum

y= -207+4

Which = -203
