Answer:
To solve the equation 8 = 3a - 4, we want to isolate the variable "a" on one side of the equation. Step 1: Start by adding 4 to both sides of the equation to get rid of the -4 on the right side: 8 + 4 = 3a - 4 + 4 This simplifies to: 12 = 3a Step 2: Next, divide both sides of the equation by 3 to solve for "a": 12/3 = 3a/3 This simplifies to: 4 = a So the solution to the equation 8 = 3a - 4 is a = 4. To check if this solution is correct, substitute "4" back into the original equation: 8 = 3(4) - 4 This simplifies to: 8 = 12 - 4 Which is true, so our solution is correct. In summary, to solve the equation 8 = 3a - 4, you add 4 to both sides to eliminate the -4, then divide both sides by 3 to solve for "a." The solution is a = 4.
