Q. −4+bx=2x+3(x+1) In the equation shown, b is a constant. For what value of b does the equation have no solutions?
Identify Structure and Condition: Identify the structure of the given equation and the condition for no solutions.The equation is in the form of a linear equation, and for it to have no solutions, the coefficients of x on both sides must be equal, and the constants must be different. This is because if the lines represented by both sides of the equation have the same slope but different y-intercepts, they are parallel and will never intersect.
Expand and Simplify: Expand the right side of the equation to simplify it.2x+3(x+1)=2x+3x+3Combine like terms.2x+3x+3=5x+3
Combine Like Terms: Set up the equation to compare the coefficients of x on both sides.For the equation to have no solutions, the coefficient of x on the left side (which is b) must be equal to the coefficient of x on the right side (which is 5).So, b must be equal to 5.
Set Up Equation for Coefficients: Check if the constants on both sides are different when b is 5. On the left side, the constant is −4, and on the right side, the constant is 3. Since −4 is not equal to 3, the condition for no solutions is satisfied when b=5.
