Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-x + 4y = -8

-5x - 4y = -16

Step 2: Solve for x

Elimination

Combine equations:                     -6x = -24Isolate x:                                        x = 4

Step 3: Solve for y

Define equation:                   -x + 4y = -8Substitute in x:                      -4 + 4y = -8Isolate y term:                       4y = -4Isolate y:                                y = -1
