Inspector Reference Rulebook
One Solution: Different \(x\) coefficients (\(a \neq c\)). Lines intersect once.
No Solution: Same \(x\) coefficients, different constants (\(b \neq d\)). False!
Infinitely Many (Identity): Identical variables and constants (\(a=c, b=d\)).
Simplify both sides fully before classifying!

Q1: \(5x + 3x - 11 = 29\) Ans: A
\(8x - 11 = 29\)
\(8x = 40 \implies \mathbf{x = 5}\)
→ a glittery pink flamingo
Q2: \(4(x - 3) = 28\) Ans: B
\(4x - 12 = 28\)
\(4x = 40 \implies \mathbf{x = 10}\)
→ did an aggressive salsa dance
Q3: \(9x - 2x + 14 = 49\) Ans: C
\(7x + 14 = 49\)
\(7x = 35 \implies \mathbf{x = 5}\)
→ the middle of the cafeteria
Q4: \(2(4x + 3) - 5x = 21\) Ans: A
\(8x + 6 - 5x = 21\)
\(3x + 6 = 21 \implies \mathbf{x = 5}\)
→ glowing neon rollerblades
Q5: \(-6x + 15 = -21\) Ans: B
\(-6x = -36\)
\(x = \frac{-36}{-6} \implies \mathbf{x = 6}\)
→ ridiculously dramatic
Q6: \(30 - 3(x + 2) = 15\) Ans: A
\(30 - 3x - 6 = 15 \rightarrow 24 - 3x = 15\)
\(-3x = -9 \implies \mathbf{x = 3}\)
→ juggled three watermelons
Q7: \(8x - 5 - 3x + 9 = 24\) Ans: B
\(5x + 4 = 24\)
\(5x = 20 \implies \mathbf{x = 4}\)
→ a golden megaphone
Q8: \(-2(3x - 5) + 4 = 26\) Ans: B
\(-6x + 10 + 4 = 26 \rightarrow -6x + 14 = 26\)
\(-6x = 12 \implies \mathbf{x = -2}\)
→ shouted “KA-CHOW!”
Q9: \(5(2x - 1) - 7 = 28\) Ans: A
\(10x - 5 - 7 = 28 \rightarrow 10x - 12 = 28\)
\(10x = 40 \implies \mathbf{x = 4}\)
→ the school principal
Q10: \(6(2x - 1) = 12x - 6\) Ans: C
\(12x - 6 = 12x - 6\)
Identical! \(\mathbf{Infinitely\ Many}\)
→ threw confetti in hair
Q11: \(7x + 10 = 7x - 4\) Ans: A
Subtract \(7x\): \(10 = -4\) (False!)
Same coeff., diff const: \(\mathbf{No\ Sol}\)
