If 5x + 3y = 21 5x+3y=21 and 2x − y = 4
2x−y=4, what is the value of x?
You asked:
Given the following equations: \[\begin{aligned}5 x + 3 y &= 21\\ 5 x + 3 y &= 21\\ 2 x - y &= 4\\ 2 x - y &= 4\end{aligned}\] Evaluate \(x\).
MathBot Answer:
The system of linear equations has exactly one solution.
The substitution is \( x = 3 \).
\[x = 3\]
