Math Problem Statement
Solution
The system of equations you're working with is:
To solve this system, we can use substitution or elimination. I'll proceed with substitution since the first equation already expresses in terms of .
Step 1: Set the two expressions for equal to each other.
Step 2: Solve for .
Subtract from both sides:
Add 5 to both sides:
Divide both sides by 2:
Step 3: Substitute into either original equation. I'll use the first equation:
Thus, the solution to the system is and , or the point .
Graphically:
The point of intersection of the two lines, according to the graphs you've provided, is indeed at , which confirms the solution.
