Answer 2

To solve the equation $\frac{12.4}{5} - \left(x + \frac{1.2}{3}\right) = \frac{7.9}{10}$, follow these steps:

Step 1: Simplify the equation by performing the arithmetic operations:

$\frac{12.4}{5} = 2.48$

$\frac{1.2}{3} = 0.4$

So, the equation becomes:

$2.48 - (x + 0.4) = 0.79$

Step 2: Remove the parentheses by distributing the negative sign:

$2.48 - x - 0.4 = 0.79$

Step 3: Combine like terms on the left side of the equation:

$2.48 - 0.4 - x = 0.79$

$2.08 - x = 0.79$

Step 4: Isolate the variable $x$ by moving $2.08$ to the right side of the equation:

$-x = 0.79 - 2.08$

$-x = -1.29$

Step 5: Solve for $x$ by multiplying both sides of the equation by -1 (to isolate $x$):

$x = 1.29$

So, the solution to the equation is $x = 1.29$.
