Step-by-step explanation:
1)x is less than 7
2)x is greater than and equal to -4
Answer:
Infinite solutions.
Step-by-step explanation:
Use the elimination method:
15x - 5y = -20
-3x + y = 4 Multiply this equation by 5:
-15x + 5y = 20 Now add this to the first equation:
0 = 0
So the 2 equations are the same and there are infinite solutions.
