The answer is taken from the variable, Step2) He should have added 3 to, rather than subtracting 3 from, both sides.
What is variable?
A variable is a placeholder symbol for a changing amount or any mathematical object. A variable can specifically represent a number, a vector, a matrix, a function, its argument, a set, or one of its elements.
A variety of issues are resolved by algebraic calculations that treat variables like explicit integers in a single computation.
For instance, the quadratic formula resolves all quadratic equations by replacing the variables that represent the coefficients with their numerical values.
A variable in mathematical logic is either a sign for an undefined term in the theory or a fundamental component of the theory that is changed without considering any potential intuitive applications.
Analyze the steps emeril used to solve for the variable to determine if he made an error. in which step did emeril make an error. Step 2: He should have added 3 to, rather than subtracting 3 from, both sides.
1. Combine like terms: 6b − 3 = −21
2. Subtraction property of equality: 6b = −24
Here he has to add 3 on both sides, to isolate the variable term.
Therefore, the answer is Step2) He should have added 3 to, rather than subtracting 3 from, both sides.
