  • 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

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

Step 3: Solve for y

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

Answer:

Step-by-step explanation:

step 1

y=2x-1,4x+6y=10  Equation

step 2

y=2x-1  solve for y

4x+6y=10  substitute

4x+6(2x-1)=10

step 3

16x-6=10

16x-6+6=10+6 add 6

16x=16

16x/16=16/16

x=1

step 4

y=2x-1  substitute

y=(2)(1)-1

y=1

your two answers are

x=1 and y=1
