Q. Combine the like terms to create an equivalent expression.9t−3t+4=□
Identify like terms: Identify like terms in the expression.Like terms are terms that contain the same variable raised to the same power. In this expression, 9t and −3t are like terms because they both contain the variable t raised to the first power.
Combine like terms: Combine the like terms by adding or subtracting their coefficients.Add the coefficients of 9t and −3t.9t−3t=(9−3)t
Simplify coefficients: Simplify the coefficients.Subtract 3 from 9 to get the coefficient for t.9−3=6So, 9t−3t simplifies to 6t.
Write simplified expression: Write the simplified expression.Combine the simplified term 6t with the constant term +4.The equivalent expression is 6t+4.
