Q. Find the missing number so that the equation has no solutions. 5x−18=____x−3
Understand Equation Solutions: Understand when an equation has no solutions. An equation has no solutions when the two sides of the equation are parallel lines, which means the coefficients of x are the same, 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.
Identify Constants: Identify the constants on both sides of the equation.The constant on the left side is −18, and the constant on the right side is −3. Since these constants are different, the equation will have no solutions if the coefficients of x are the same.
Determine Missing Number: Determine the missing number.The missing number is the coefficient of x on the right side of the equation that will make the equation have no solutions. Based on Step 2, the missing number is 5.
