Math Problem Statement
x=y-1 3x=2y find the points
Solution
To find the points where the system of equations intersect, let's solve the following system:
Step 1: Substitute into
Since is already defined as in the first equation, we can substitute this into the second equation:
Step 2: Solve for
Expand and simplify the equation:
Subtract from both sides:
Step 3: Find using
Substitute back into the first equation:
Solution
The solution is the point where the two lines intersect:
