Answer:
Infinitely many.
Step-by-step explanation:
3x + 2y = 4
-6x - 4y = -8
Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.
Answer: 1 is 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Multiply the numbers 2 ( x - 11 ) * 2 = 128
4 ( x - 11 ) = 128
Distribute 4 ( x - 11 ) = 128
4x - 44 = 128
Add 44 to both sides 4x - 44 = 128
4x - 44 + 44 = 128 + 44
Simplify - Add the numbers
4x - 44 + 44 = 128 + 44
4x = 128 + 44
- Add the numbers
4x = 128 + 44
4x = 172
Divide both sides by the same factor 4x = 172
4x/4 = 172/4
Simplify
- Cancel terms that are in both the numerator and denominator
4x/4 = 172/4
x = 172/4
-Divide the numbers
x = 172/4
x = 43
