Math Problem Statement
Solution
The system of equations from the image is:
We can solve this system of equations using substitution or elimination. Let's proceed with substitution since the first equation is already solved for .
Step 1: Substitute the expression for from equation (1) into equation (2):
Now, simplify the equation: Subtract 6 from both sides: Divide by 10:
Step 2: Substitute back into equation (1) to find :
Final Solution:
Would you like further details on the steps? Here are 5 related questions for practice:
- How would you solve the system using the elimination method instead?
- What does the solution represent geometrically for the two equations?
- How can you verify the solution by substituting and into both original equations?
- Can you rewrite both equations in standard form and identify their slopes and intercepts?
- How would the system change if the second equation had a different constant term?
Tip: Always check your solution by substituting it back into the original system of equations.
