Answer 2

To solve the equation 9a - 150/4 + 18 = 3, let's break it down step by step:

Step 1: Simplify the expression on the left side of the equation. - First, let's simplify 150/4. Dividing 150 by 4 gives us 37.5. - So, the equation becomes: 9a - 37.5 + 18 = 3.

Step 2: Combine like terms on the left side of the equation. - The terms -37.5 and 18 can be combined to give -19.5. - So, the equation becomes: 9a - 19.5 = 3.

Step 3: Isolate the variable on one side of the equation. - To isolate the variable 9a, we need to get rid of the constant term -19.5 on the left side of the equation. - We can do this by adding 19.5 to both sides of the equation. - The equation becomes: 9a - 19.5 + 19.5 = 3 + 19.5. - Simplifying further, we have: 9a = 22.5.

Step 4: Solve for the variable. - To solve for the variable a, we need to divide both sides of the equation by 9. - The equation becomes: (9a)/9 = 22.5/9. - Simplifying further, we have: a = 2.5.

Therefore, the solution to the equation 9a - 150/4 + 18 = 3 is a = 2.5.
