Q. Find the missing number so that the equation has no solutions.−5x+4=____x−2
Analyze the equation: Analyze the equation -5x + 4 = ____x - 2 to determine when it has no solutions.An equation has no solutions when the coefficients of the variable are the same on both sides, but the constants are different.
Compare coefficients of x: Compare the coefficients of x on both sides of the equation.The coefficient of x on the left side is −5. For the equation to have no solutions, the coefficient of x on the right side must also be −5.
Check constants: Check the constants on both sides of the equation.The constant on the left side is +4, and the constant on the right side is −2. Since these constants are different, if the coefficients of x are the same, the equation will have no solutions.
Conclude missing number: Conclude the missing number.The missing number is the coefficient of x on the right side that will make the equation have no solutions. Based on our analysis, the missing number is −5.
