Attempt following question by selecting a choice to answer.
Which of the following equations would you use to isolate the variable? 10 + 13 = 1 [Equation 1] - 9 = - 8 [Equation 2]D B
Both Equation 1 and Equation 2
Neither Equation 1 nor Equation 2
Step 1: The coefficient of in Equation 2 is 1, so it is easier to isolate the variable.
Step 2: So, Equation 2 can be used for isolating the variable.
