Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x + 5

y = -3x

Step 2: Solve for x

Substitution

Substitute in y:                     -3x = 2x + 5Add 3x on both sides:         0 = 5x + 5Subtract 5 on both sides:    -5 = 5xDivide 5 on both sides:        -1 = xRewrite:                                 x = -1

Step 3: Solve for y

Define equation:                     y = -3xSubstitute in x:                        y = -3(-1)Multiply:                                   y = 3
