5.11, i used the produatecr formula
<span>4*((‑(8*x))+5)-(‑(33*x))-26
sorry if this is to hard to understand
</span>
let "a number" = n
"3 times a number" = 3n
"the sum of 12" = "+ 12
Combine the two terms
3n + 12, or (B) is your answer
hope this helps
In order to eliminate the y terms, the y terms must be reciprocals.
The first equation has 9y.
To eliminate y, you need to add to it -9y.
The second equation has y. In order for the second equation to have -9y, you must multiply both sides of the second equation by -9.
Answer: D -9
20 + 10x = 15x +16 +5
15x+21 =20+10x
5x = -1
X= -0.2
