Q. Find an expression which represents the difference when (−4x−6y) is subtracted from (−3x+4y) in simplest terms.Answer:
Distribute negative sign: To find the difference when one expression is subtracted from another, we combine like terms after changing the sign of each term in the expression being subtracted.(−3x+4y)−(−4x−6y)
Simplify expression: First, distribute the negative sign to the terms in the second expression.(−3x+4y)−(−4x)−(−6y)
Combine like terms: Simplify the expression by removing the parentheses and changing the signs of the terms that were negative in the second expression. (−3x+4y)+4x+6y
Perform addition: Combine like terms by adding the coefficients of the x terms and the y terms separately.(−3x+4x)+(4y+6y)
Simplify further: Perform the addition of the coefficients. 1x+10y
Simplify further: Perform the addition of the coefficients. 1x+10ySince 1x is the same as x, we can simplify the expression further.x+10y
