Answer:
n = 14
Step-by-step explanation:
7n +9 = -1+6(n+4)
Distribute
7n+9 = -1 +6n+24
Combine like terms
7n +9 = 6n +23
Subtract 6n from each side
7n -6n+9 = 6n-6n +23
n+9 = 23
Subtract 9 from each side
n+9-9=23-9
n = 14
U have to put it together and then multiply it by 2 on the left one and then u will get your answer
<span>{4x + y = 2
{−2x + y = 5
--------------------subtract
6x = -3
x = -1/2
</span>4x + y = 2
4(-1/2) + y = 2
-2 + y = 2
y = 4
x = -1/2 and y = 4
answer
<span>(−1/2, 4)</span>
