Math Problem Statement
solution for y=-1/2x+2 and y=1/4x+2
Solution
To find the solution for the system of linear equations:
we need to find the point where these two lines intersect.
Step 1: Set the equations equal to each other
Since both equations are equal to , we can set them equal to each other:
Step 2: Eliminate the constants
Subtract 2 from both sides:
Step 3: Solve for
To eliminate the fractions, multiply every term by 4:
This simplifies to:
Now, add to both sides:
Simplifying this gives:
Dividing by 3:
Step 4: Solve for
Substitute into one of the original equations (e.g., ):
Final Answer
The solution to the system of equations is the point where they intersect:
