I believe the answer is 4/15.
We write to expressions since there are two unknown here which is x and y. The first expression is the <span>sum of two numbers, x and y, is 12.
x + y = 12
The second expression is that the </span><span>difference of x and two times y is 6.
x -2y = 6
Therefore, the values of x and y are 10 and 2.</span>
Answer: 2 + 1 = 3 2 x 1 =2
Step-by-step explanation: + 7 = 7
13. Is 18
15. Is 86
17 is 5
19 is 15
21 is 24
23 is 29
n = 2
distribute and simplify left side of equation
50 - 10n - 1 = 29
49 - 10n = 29 ( subtract 49 from both sides )
- 10n = 29 - 49 = - 20
n =
= 2
