Answer:
1. -49
2. -8
Step-by-step explanation:
1. For there to be infinite solutions the left and right sides must be identical.
-7(2x + 7) + 10x
= -14x - 49 + 10x
= -4x - 49
Thus the blank space must contain -49.
2. For there to be no solution the terms in x must be the same on both sides and the numbers different.
As you see the numbers are different. The answer is the x term on the left side = -8x, as the x terms on the right simplify to -8x.
-8 goes in the blank space.
