wha expression is equivalent ti -21+28x
7(-3+4x)
That what I do here
The expression -21 + 28x can be simplified by combining like terms. Since -21 is a constant term and 28x is a variable term, we cannot combine them. Therefore, the expression -21 + 28x is already simplified and does not have an equivalent expression.
The given expression is -21 + 28x. To find an expression that is equivalent to this expression, we need to simplify it further.
To simplify the expression, we combine like terms by adding or subtracting the coefficients of the same variable. In this case, the only like term we have is -21 and 28x. So, we can rewrite the expression as:
28x - 21
Therefore, the equivalent expression to -21 + 28x is 28x - 21.
