HELP ME PLEASE PLEASE

Ymorist [56]

Answer:

The value of x is 7 and y is 14.

Step-by-step explanation:

The steps are :

$- 3x + y = - 7 - - - (1)$

$y = x + 7 - - - (2)$

$(2)→(1)$

$- 3x + (x + 7) = - 7 \\ - 3x + x + 7 = - 7 \\ - 2x = - 14 \\ x = 7$

$substitute \: x = 7 \: \: into \: \: (2)$

$y = 7 + 7 \\ y = 14$

$\bf 12,\underline{351}\impliedby \textit{3 hundreds, and 51 units, let's round that}
\\\\\\
\begin{array}{llll}
300----- 50-----400\\
\qquad \qquad \uparrow\qquad \qquad \qquad \uparrow \\

\begin{array}{llll}
anything\ here\\
rounds\ up\ to\\
300
\end{array}\quad
\begin{array}{llll}
anything\ here\\
rounds\ up\ to\\
400
\end{array}
\end{array}
\\\\\\
\textit{therefore, the hundreds value of 300, the 51 tips it over to 400}
\\\\\\
12,\underline{400}$
