Christiana has a debt of \( \$ 882 \) to pay off with no interest added. If she pays \( \$ 63 \) each month, how long will it take her to pay back the loan? The equation can be written as: \( y=-63 x+882 \) Solve the problem by solving for the x-intercept. 14 months 13 months 15 months 12 months

\( 1 \leftarrow \quad \begin{array}{l}\text { Solve the system of equations by the substitution method. } \\ \begin{aligned} 4 x+2 y & =-154 \\ x-5 y & =0\end{aligned}\end{array} \)

\( 1 \leftarrow \quad \begin{array}{r}\text { Solve the system of equations by the substitution method. } \\ \begin{aligned} x+y & =-2 \\ y & =-2 x\end{aligned}\end{array} \)

\( 5(x+6)=-50 \) then \( x= \)

What should be, subtracted from \( 8 x-3 y+4 \) to get \( 3 x-2 y+4 \).

\( 1 \leftarrow \begin{array}{l}\text { Determine whether the ordered pair }(2,6) \text { is a solution of the system. } \\ \begin{array}{l}x+y=8 \\ x-y\end{array}\end{array} \)
