Answer 2

To solve the equation 3а - 2(25 - а) = 55, follow these steps:

Step 1: Distribute the -2 on the left side of the equation. Step 2: Combine like terms. Step 3: Isolate the variable 'а' on one side of the equation.

Let's proceed with the steps:

Step 1: 3а - 2(25 - а) = 55

Expanding -2(25 - а) gives: 3а - 2 * 25 + 2а = 55

Step 2: Now combine like terms on the left side: 3а + 2а - 50 = 55

Step 3: Next, combine the constant terms on the left side: 5а - 50 = 55

Step 4: Now, isolate the variable 'а' by moving the constant term to the right side: 5а = 55 + 50 5а = 105

Step 5: Finally, solve for 'а' by dividing both sides by 5: а = 105 / 5 а = 21

So the solution to the equation is а = 21.
