Q. (4x+3)−(5x−7)=ax+bIn the given equation, b is a constant. What is the value of b ?
Distribute and Simplify: First, we need to simplify the left-hand side of the equation by distributing the negative sign to the terms within the second set of parentheses. This means we will subtract both 5x and −7 from 4x and 3, respectively.Calculation: (4x+3)−(5x−7)=4x+3−5x+7
Combine Like Terms: Next, we combine like terms on the left-hand side. This involves combining the x terms and the constant terms separately.Calculation: (4x−5x)+(3+7)=−x+10
Determine Coefficients: Now that we have simplified the left-hand side, we can see that the equation is in the form of −x+10=ax+b. Since there is no x term on the right-hand side, we can infer that a=−1. However, we are only interested in the value of b, which is the constant term.Calculation: b=10
Find Constant Term: We have determined that the value of b is 10, which is the constant term on the left-hand side after simplification.
