  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

  1. Substitute in y:                   -10x = -7x + 6
  2. Add 10x to both sides:      0 = 3x + 6
  3. Isolate x term:                    -6 = 3x
  4. Isolate x:                             -2 = x
  5. Rewrite:                              x = -2

Step 3: Solve for y

  1. Define equation:                    y = -10x
  2. Substitute in x:                       y = -10(-2)
  3. Multiply:                                  y = 20

Answer:

x = -2

y = 20

Step-by-step explanation:

y = -7x + 6

y = -10x​

y = -10x

-7x + 6 = -10x

3x = -6

x = -2

y = -7x + 6

y = -7 ( -2 ) + 6

y = 14 + 6

y = 20
