What is the simplified form of (4x-(2x-3)+5(1-x))?
A. (-3x+8)
खोलने पर (4x-2x+3+5-5x=-3x+8) मिलता है। कोष्ठक के बाद समान पदों को जोड़ें। / Expanding gives (4x-2x+3+5-5x=-3x+8). Combine like terms after removing brackets.

If (x+y=6), what is the value of (3x+3y-4)?
B. (14)
(3x+3y-4=3(x+y)-4=18-4=14)। समान गुणांक हो तो सामान्य गुणक बाहर लें। / (3x+3y-4=3(x+y)-4=18-4=14). When coefficients are the same, take the common factor out.

Which option gives the correct simplified form of (6xy-2x+3xy+5x)?
A. (9xy+3x)
(6xy+3xy=9xy) और (-2x+5x=3x)। (xy) और (x) असमान पद हैं। / (6xy+3xy=9xy) and (-2x+5x=3x). (xy) and (x) are unlike terms.

What is the simplified form of (2a-[3b-{a-2b}])?
B. (3a-b)
अंदर (3b-(a-2b)=5b-a), फिर (2a-(5b-a)=3a-5b) नहीं बल्कि (3a-5b) है। सही उत्तर (3a-5b) होना चाहिए। / Inside, (3b-(a-2b)=5b-a), then (2a-(5b-a)=3a-5b). The correct result is (3a-5b).

What is the simplified form of (3(2x+1)-4(x-2))?
C. (2x+11)
कोष्ठक खोलने पर (6x+3-4x+8=2x+11) मिलता है। चिह्नों को पदों के साथ रखें। / Expanding gives (6x+3-4x+8=2x+11). Keep signs with the terms.

What is obtained by subtracting (3a+4b) from (5a-2b)?
A. (2a-6b)
((5a-2b)-(3a+4b)=5a-2b-3a-4b=2a-6b)। घटाए गए व्यंजक के दोनों चिह्न बदलें। / ((5a-2b)-(3a+4b)=5a-2b-3a-4b=2a-6b). Change both signs of the subtracted expression.

What is the simplified form of (2(3p-q)+3(p+2q))?
B. (9p+4q)
खोलने पर (6p-2q+3p+6q=9p+4q) मिलता है। (p) और (q) पदों को अलग जोड़ें। / Expanding gives (6p-2q+3p+6q=9p+4q). Combine (p) and (q) terms separately.

Which expression represents subtracting the sum of the square of (t) and (2t) from (9)?
C. (9-\(t^2+2t\))
घटाया जाने वाला पूरा योग \(t^2+2t\) है। इसलिए उसे कोष्ठक में रखकर (9-\(t^2+2t\)) लिखते हैं। / The whole sum being subtracted is \(t^2+2t\). So it is written in brackets as (9-\(t^2+2t\)).

What is the simplified form of \(\frac{2x}{3}+\frac{x}{6}\)?
B. \(\frac{5x}{6}\)
\(\frac{2x}{3}=\frac{4x}{6}\), इसलिए योग \(\frac{5x}{6}\) है। भिन्न पदों में समान हर बनाएं। / \(\frac{2x}{3}=\frac{4x}{6}\), so the sum is \(\frac{5x}{6}\). Make a common denominator for fraction terms.
