Transcript text: Which ordered pair is the solution to this system of equations?
\[
\begin{array}{l}
y=x+4 \\
x+y=2
\end{array}
\]
$(-4,0)$
$(0,2)$
$(-1,3)$
$(1,5)$
Solution
Solution Steps
Step 1: Substitute \( y = x + 4 \) into the second equation
Substitute \( y = x + 4 \) into \( x + y = 2 \):
\[
x + (x + 4) = 2
\]
Step 2: Simplify the equation
Combine like terms:
\[
2x + 4 = 2
\]
Step 3: Solve for \( x \)
Subtract 4 from both sides:
\[
2x = -2
\]
Divide both sides by 2:
\[
x = -1
\]
Step 4: Find \( y \) using \( y = x + 4 \)
Substitute \( x = -1 \) into \( y = x + 4 \):
\[
y = -1 + 4 = 3
\]
Step 5: Verify the solution
The solution is \( (-1, 3) \), which matches one of the given options.
