Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x - 1

4x + 6y = 10

Step 2: Solve for x

Substitution

Substitute in y:                    4x + 6(2x - 1) = 10Distribute 6:                        4x + 12x - 6 = 10Combine like terms:           16x - 6 = 10Add 6 to both sides:           16x = 16Divide 16 on both sides:     x = 1

Step 3: Solve for y

Define equation:                    y = 2x - 1Substitute in x:                       y = 2(1) - 1Multiply:                                  y = 2 - 1Subtract:                                 y = 1
