Answer:
B
Step-by-step explanation:
A. 37 isn't a number sentence
B. 49 + (-12) = 49-12. They're the same thing because 49 minus 12 can also be written as 49 plus negative 12
C. 49 + 12 doesn't equal 49-12
D. 12- 49 = -37 which isn't equivalent to 49-12.
Hope this helps!!!
Answer:
Infinite solutions
Step-by-step explanation:
<em><u>Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:</u></em>
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n - 2
<em><u>Add like terms (2n and 4n):</u></em>
6n - 2 = 6n - 2
<em><u>Subtract 6n from both sides:</u></em>
-2 = -2
Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.
7x+12+6x-2=-4
7x-6x=-4-12+2
13x=-14
x=-14 divide 13
x=-14 over 13 put 14 over 13 in a fraction
