Math Problem Statement
Solve the system of equations graphed on the coordinate axes below. y, equals, start fraction, 3, divided by, 2, end fraction, x, minus, 1 y= 2 3 x−1 y, equals, minus, start fraction, 3, divided by, 2, end fraction, x, plus, 5 y= − 2 3 x+5
Solution
The system of equations given is:
To solve this system of equations, we need to find the point of intersection, which means solving for and where both equations are equal.
Step 1: Set the equations equal to each other
Since both expressions represent , we can set them equal to each other:
Step 2: Solve for
Now, add to both sides to eliminate the term from the right side:
This simplifies to:
Next, add 1 to both sides:
Now, divide both sides by 3:
Step 3: Solve for
Now that we have , substitute it into either of the original equations to find . I'll use the first equation:
Simplify:
Final Solution:
The solution to the system of equations is .
