Math Problem Statement

Solve the system of equations: y = x + 8 and 4x - 2y = -12.

Solution

The system of equations provided in the image is:

  1. y=x+8y = x + 8
  2. 4x2y=124x - 2y = -12

Solving the system of equations:

Step 1: Substitute y=x+8y = x + 8 into the second equation.

The second equation is: 4x2y=124x - 2y = -12 Substitute y=x+8y = x + 8: 4x2(x+8)=124x - 2(x + 8) = -12

Step 2: Simplify the equation.

4x2x16=124x - 2x - 16 = -12 2x16=122x - 16 = -12

Step 3: Solve for xx.

2x=12+162x = -12 + 16 2x=42x = 4 x=2x = 2

Step 4: Solve for yy using y=x+8y = x + 8.

y=2+8y = 2 + 8 y=10y = 10

Solution:

The solution to the system of equations is: x=2,y=10x = 2, \, y = 10

Would you like me to explain this process in more detail or explore another method?

Follow-Up Questions:

  1. What method would you like to use next, such as elimination or graphing?
  2. Would you like a verification of the solution by substituting back into both equations?
  3. How does substitution compare to elimination for solving systems of equations?
  4. Can you extend this to solve three-variable systems?
  5. Would you like a visual graph representation of the solution?

Tip:

When solving systems of equations, substitution is particularly useful when one equation is already solved for one variable.
