Answer:To find expressions that are equivalent to -3w + 9 + 7w - 3, we can simplify and combine like terms.
Given expression: -3w + 9 + 7w - 3
Step 1: Combine the like terms (-3w and 7w) by adding their coefficients:
-3w + 7w = 4w
Step 2: Combine the constant terms (9 and -3) by adding or subtracting them:
9 - 3 = 6
Step 3: Rewrite the expression with the simplified terms:
4w + 6
Therefore, expressions that are equivalent to -3w + 9 + 7w - 3 are 4w + 6.
