Final answer:
The point (-1,1) is not a solution to either of the equations y = 2x - 3 or x + y = 7, as substituting the point into both equations results in incorrect equations.
Step-by-step explanation:
The student has asked to solve the given equations and determine if the point (-1,1) is a solution to these equations. The equations are: y = 2x - 3 and x + y = 7. We need to check if the given point satisfies both equations.
For the first equation:
- Substitute x = -1 into y = 2x - 3: y = 2(-1) - 3, y = -2 - 3, y = -5.
Since the y-value of the point is 1, and we found y to be -5, the point does not satisfy the first equation, y = 2x - 3.
For the second equation:
- Substitute x = -1 and y = 1 into x + y = 7: -1 + 1 = 7, 0 = 7, which is false.
Since the point (-1,1) does not satisfy the second equation, x + y = 7, it is not a solution to either equation.
