Identify Equation: Identify the original equation that we need to compare the other equations to. The original equation is 8 = s + t.Compare with (A): Compare the original equation to choice (A) 17 = s + t + 9. To determine if (A) is equivalent to the original equation, subtract 9 from both sides of (A). 17 - 9 = s + t + 9 - 9 8 = s + t (A) is equivalent to the original equation.Compare with (B): Compare the original equation to choice (B) 15 = 9 + s + t. To determine if (B) is equivalent to the original equation, subtract 9 from both sides of (B). 15 - 9 = 9 + s + t - 9 6 = s + t (B) is not equivalent to the original equation.Compare with (C): Compare the original equation to choice (C) 12 = 4 + s + t. To determine if (C) is equivalent to the original equation, subtract 4 from both sides of (C). 12 - 4 = 4 + s + t - 4 8 = s + t (C) is equivalent to the original equation.Compare with (D): Compare the original equation to choice (D) 16 = 8 + s + t. To determine if (D) is equivalent to the original equation, subtract 8 from both sides of (D). 16 - 8 = 8 + s + t - 8 8 = s + t (D) is equivalent to the original equation.

Select all of the equations below that are equivalent to: $\newline$ $8 = s + t$ $\newline$ Use properties of equality. $\newline$ Multi-select Choices: $\newline$ (A) $17 = s + t + 9$ $\newline$ (B) $15 = 9 + s + t$ $\newline$ (C) $12 = 4 + s + t$ $\newline$ (D) $16 = 8 + s + t$
