WHAT IT THE ANSWER🙄🙄😕😕😬😬😬😤😤😒😒😒😔😠👻😿🐱👤
To solve the equation 12.4x + 7.7 = 82.1, we need to isolate the variable x. Here's how you can do it:
Step 1: Subtract 7.7 from both sides of the equation to get rid of the constant term on the left side:
12.4x + 7.7 - 7.7 = 82.1 - 7.7
This simplifies to:
12.4x = 74.4
Step 2: Divide both sides of the equation by 12.4 to isolate x:
12.4x/12.4 = 74.4/12.4
This simplifies to:
x = 6
So the solution to the equation 12.4x + 7.7 = 82.1 is x = 6.
next step: subtract 7.7 to get
12.4x = 74.4
