-6x + 6y =6
-6x + 3y = -12
You would multiply the bottom equation by -1 to make -6x a positive so you can eliminate it.
-6x + 6y = 6
 6x + -3y = 12
Eliminate -6y and add 6y to -3y as well as 6 and 12.
0 +  3y = 18
3y = 18
divide both sides by 3
y = 6 
 
now that you know the value of y it will be easy to find x :)

-6x + 6y = 6
-6x + 3y = -12

✨ You need to eliminate a variable, so I'll use -1 to multiply the first equation by.

6x - 6y = -6
-6x + 3y = -12

-3y = -18

✨ y = 6

6x - 36 = -6

6x = 30

✨ x = 5

✨ The solution is (5,6) ✨

The fifth term of an arithmetic sequence is 100, and the common difference is 4. Find the first three terms of the sequence.
Ronch [10]
\bf a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term}\\
d=\textit{common difference}\\
--------------\\
a_5=100\\
n=5\\
d=4
\end{cases}
\\\\\\
a_5=a_1+(5-1)4\implies 100=a_1+(5-1)4
\\\\\\
\textit{solve for }a_1\textit{ to find the first term}

then use the common difference "d", to get the 2nd and 3rd terms

-------------------------------------------------------------------------------------------

\bf a_5=a_1+(5-1)4\implies 100=a_1+(5-1)4\implies 100=a_1+(4)4
\\\\\\
100=a_1+16\implies 100-16=a_1\\\\ 84=a_1\quad 
\begin{cases}
a_1=&84\\
a_2=84+4\to &88\\
a_3=88+4\to  &92
\end{cases}

7/3 of y is 5 5/6<br> pls solve!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Ira Lisetskai [31]

Answer:

<em>2.5</em>

Step-by-step explanation:

\frac{7}{3} y = 5\frac{5}{6}

<em>y</em> = \frac{35}{6} ÷ \frac{7}{3} = \frac{35}{6} × \frac{3}{7} = \frac{5}{2} = <em>2.5</em>
