Q. Which of the following is an equivalent form of (2x+3)−(7x−6)?Choose 1 answer:(A) −5x−3(B) −5x+9(C) 4x(D) 9x−3
Distribute negative sign: Subtract the second expression from the first expression by distributing the negative sign across the second expression. This means we change the sign of each term inside the parentheses that is being subtracted.(2x+3)−(7x−6)=2x+3−7x+6
Combine like terms: Combine like terms by adding or subtracting the coefficients of the same variable and the constant terms. 2x−7x+3+6=−5x+9
Check answer choices: Check the answer choices to see which one matches the simplified expression.The correct answer is (B) −5x+9.
