Systems of linear equations online practice complete this assessment review what you've learned it will not count towards your brain is five, -1 a solution to the system of these linear equations x + y = 4 and 2x + 3y = 7 why
Yes, (-1, 5) is a solution to the system of linear equations x + y = 4 and 2x + 3y = 7.
To verify this, let's substitute x = -1 and y = 5 into both equations:
1. x + y = 4
-1 + 5 = 4
4 = 4 (True)
2. 2x + 3y = 7
2(-1) + 3(5) = 7
-2 + 15 = 7
13 = 7 (False)
Since the second equation does not hold true when x = -1 and y = 5, (-1, 5) is not a solution to the system of linear equations.
