Q. 32−5x=bx+31In the equation shown, b is a constant. For what value of b does the equation have no solutions?Choose 1 answer:(A) 5(B) 0(C) −5(D) 32
Isolate variable x: We start by trying to isolate the variable x on one side of the equation to see if we can solve for x in terms of b.32−5x=bx+31
Subtract constants: Subtract (31) from both sides to get the x terms on one side and the constants on the other.(32)−(31)−5x=bx
Combine constants: Combine the constants on the left side.(31)−5x=bx
Add x terms: Add 5x to both sides to get all the x terms on one side.31=bx+5x
Factor out x: Factor out x on the right side.31=x(b+5)
Set coefficient to zero: For the equation to have no solutions, the right side must never equal the left side for any value of x. This can only happen if the coefficient of x on the right side is zero, because any non-zero number times x could potentially equal (31). So, we set the coefficient of x to zero. b+5=0
Solve for b: Subtract 5 from both sides to solve for b.b=−5
