Q. Select all of the equations below that are equivalent to:12=xyUse properties of equality.Multi-select Choices:(A) 2=xy−9(B) 7=xy−5(C) 4=xy−8(D) 2=xy−10
Original Equation: To determine if an equation is equivalent to 12=xy, we can manipulate the original equation and compare it to the choices given. We start with the original equation:12=xyWhich operation should be used to compare with the choices?We should subtract a value from both sides of the equation to match the format of the choices.
Comparison with Choice (A): Let's compare the original equation with choice (A):12=xySubtract 9 from both sides:12−9=xy−93=xy−9This does not match choice (A), which states 2=xy−9.
Comparison with Choice (B): Now let's compare the original equation with choice (B):12=xySubtract 5 from both sides:12−5=xy−57=xy−5This matches choice (B), which states 7=xy−5.
Comparison with Choice (C): Next, let's compare the original equation with choice (C): 12=xy Subtract 8 from both sides: 12−8=xy−8 4=xy−8 This matches choice (C), which states 4=xy−8.
Comparison with Choice (D): Finally, let's compare the original equation with choice (D): 12=xy Subtract 10 from both sides: 12−10=xy−10 2=xy−10 This does not match choice (D), which states 2=xy−10.
