Let's simplify the equation step by step.
The equation given is:
\[ 7.7(1) = -0.3 + 48.3 \]
Calculating the right side first:
\[ -0.3 + 48.3 = 48.3 - 0.3 = 48 \]
Now we have:
\[ 7.7 = 48 \]
At this point, it looks like we need to find the value of \( x \) that satisfies this equation.
The left side \( 7.7(1) \) does not contain \( x \), and as it stands, the two sides are not equal. The equation suggests that there may have been some misunderstanding since 7.7 does not equal 48.
Since \( 7.7 \) does not equal \( 48 \), we need more context or a redefining of the variables, since this equation cannot hold true as presented.
If this was meant to imply a relationship or was part of a larger equation where \( x \) was involved, please provide that additional context so we can solve for \( x \) properly.
As it is, none of the options (A, B, C, D) can be determined to be correct from this equation since it's incorrect as stated.
