Question

VI.Check the given values are solutions of the equations or not.
1. 3x+2y-5=7 for x=2, y=3
2. a-b+c-d =18 for a=-4, b=5, c=9, d=-18
3. xy(x+5) +z= -151 for x = 5, y = 3, z = 1
4. xy(x+5) -z= 150 for x = 5, y = 3, z = 1
5. = -2 for a=-2, b=-6

Answer 1

Step-by-step explanation:

1 . 3x+2y-5=7 for x=2, y=3

2. a-b+c-d =18 for a=-4, b=5, c=9, d=-18

3. xy(x+5) +z= -151 for x = 5, y = 3, z = 1

4. xy(x+5) -z= 150 for x = 5, y = 3, z = 1

5. = -2 for a=-2, b=-6
