Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-6x + 5y = 34

-6x - 10y = 4

Step 2: Rewrite Systems

-6x + 5y = 34

Multiply everything by -1:                    6x - 5y = -34

Step 3: Redefine Systems

6x - 5y = -34

-6x - 10y = 4

Step 4: Solve for y

Elimination

Combine 2 equations:                    -15y = -30Divide -15 on both sides:                y = 2

Step 5: Solve for x

Define equation:                    -6x - 10y = 4Substitute in y:                       -6x - 10(2) = 4Multiply:                                  -6x - 20 = 4Add 20 on both sides:          -6x = 24Divide -6 on both sides:       x = -4
