Answer:
2-15w
10+w
3w+1
8-w
Explanation:
the main thing to note is the difference between an expression and an equation.
an expression is simply a combination of a finite set of terms with operations like addition, subtraction, multiplication and division.
an equation connects two expressions together using the = symbol, which means whatever is to the left of this symbol is the same as whatever is to the right of the symbol.
what matters is equations have = while expressions don't
now, we do them step by step.
2-15w is an expression.
10+6w is an expression.
3w+1 is an expression.
4w=0 is in equation. it has =
8-w is an expression.
17=w is an equation. again, it has =
