  1. Identify Equivalent Expression: To find an expression that has the same value as 8y+(2x)8y+(-2x), we need to look for an expression that is algebraically equivalent.
  2. Simplify Expression: The expression 8y+(2x)8y+(-2x) can be simplified by removing the parentheses, which gives us 8y2x8y - 2x.
  3. Compare with Given Choices: Now, let's compare the simplified expression 8y2x8y - 2x with the given choices:\newline11. 2x+8y2x + 8y is not equivalent because the terms are not in the same order, and the sign in front of 2x2x is positive instead of negative.\newline22. 8y+2x8y + 2x is not equivalent because the sign in front of 2x2x is positive instead of negative.\newline33. 8y(2x)8y - (-2x) is equivalent because the double negative on 2x2x becomes positive, resulting in 8y+2x8y + 2x, which is the same as 8y2x8y - 2x.\newline44. 2x(8y)-2x - (-8y) is not equivalent because the double negative on 2x+8y2x + 8y00 becomes positive, resulting in 2x+8y2x + 8y11, which is not the same as 8y2x8y - 2x due to the order of the terms.
  4. Determine Equivalence: Therefore, the expression that has the same value as 8y+(2x)8y+(-2x) is 8y(2x)8y - (-2x), which simplifies to 8y+2x8y + 2x.
