Final answer:
The first step to solve the equation (4/7) × -5 = -13 is a) Multiply both sides by 7 to eliminate the fraction and isolate the variable.
Step-by-step explanation:
The first step needed to solve the equation (4/7) × -5 = -13 is to isolate the variable on one side. To do this, we need to eliminate the fraction by multiplying both sides by the denominator of the fraction. The correct answer is a) Multiply both sides by 7. This will give us 4 × -5 = -91, which simplifies to -20 = -91. Since this is not possible, there seems to be an error in the original problem statement.
