Step-by-step explanation:

Step 1: Define Systems

y = 7x + 10

y = -4x - 23

Step 2: Solve for x

Substitution

  1. Substitute in y:                                                                                                7x + 10 = -4x - 23
  2. [Addition Property of Equality] Add 4x on both sides:                                11x + 10 = -23
  3. [Subtraction Property of Equality] Subtract 10 on both sides:                     11x = -33
  4. [Division Property of Equality] Divide 11 on both sides:                               x = -3

Step 3: Solve for y

  1. Define original equation:                                                                               y = 7x + 10
  2. Substitute in x:                                                                                                y = 7(-3) + 10
  3. Multiply:                                                                                                           y = -21 + 10
  4. Add:                                                                                                                 y = -11
(-3,-11) that’s your answer hope it helps
