Solve for a. 2.71=-0.9 a-0.8 Answer: a=

Add Constant Term: Which operation should be used to isolate a? In 2.71 = -0.9a - 0.8, we should first add 0.8 to both sides to move the constant term from the right side to the left side. Add 0.8 to both sides. Calculation: 2.71 + 0.8 = -0.9a Math error check: Calculate Sum: Find the sum on the left side of the equation. Calculate 2.71 + 0.8. Calculation: 2.71 + 0.8 = 3.51 Math error check: Divide by Coefficient: Now we have 3.51 = -0.9a. Which operation should be used to isolate a? We should divide both sides by -0.9 to solve for a. Divide by -0.9. Calculation: 3.51 / -0.9 = a Math error check: Find Value of a: Find the value of a. Calculate 3.51 / -0.9. Calculation: 3.51 / -0.9 ≈ -3.9 Math error check:
