• Solving systems of equations using substitution/elimination

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

Answer 2
