Solve for X:
To solve this problem, we'll follow these steps:
Let's execute each step:
Step 1: The original equation is .
Subtract 3.4 from both sides:
This simplifies to:
.
Step 2: Divide both sides by 6 to solve for :
.
This simplifies to:
.
Therefore, the solution to the problem is , which matches choice 3.

Solve for X:
\( x - 3 + 5 = 8 - 2 \)
You follow the reverse order of operations! Since addition was the last operation applied to x, you undo it first. Think of it as peeling an onion - remove the outer layer (addition) before the inner layer (multiplication).
Look at what's happening to the variable x. Here, x is multiplied by 6, then 3.4 is added. To solve, do the opposite in reverse order: subtract first, then divide!
Not at all! Decimals work exactly like whole numbers in equations. 15.4 - 3.4 = 12 is just as straightforward as any subtraction you've done before.
Use the substitution check: Replace x with your answer in the original equation. Calculate step by step: 12 + 3.4 = 15.4. It matches the right side!
That's completely normal! Many equations have fractional or decimal answers. The key is following the correct steps - the answer will be whatever it needs to be.
