Answer 2

To solve these equations, we'll work through each one step by step.

Equation A: $19x + 9.3 + 45x = 105.3$

First, combine like terms on the left side:

$19x + 45x + 9.3 = 105.3$

Now, add the coefficients of $x$:

$64x + 9.3 = 105.3$

Next, subtract 9.3 from both sides to isolate the term with $x$:

$64x = 105.3 - 9.3$ $64x = 96$

Now, divide both sides by 64 to solve for $x$:

$x = \frac{96}{64}$ $x = 1.5$

So, the solution to Equation A is $x = 1.5$.

Equation 6: $86.4 ÷ (35.5 - 7x) = 16$

First, isolate the denominator on the left side by multiplying both sides by $(35.5 - 7x)$:

$86.4 = 16(35.5 - 7x)$

Now, distribute 16 on the right side:

$86.4 = 568 - 112x$

Next, isolate the term with $x$ by subtracting 568 from both sides:

$-481.6 = -112x$

Finally, divide both sides by -112 to solve for $x$:

$x = \frac{-481.6}{-112}$

$x = 4.3$

So, the solution to Equation 6 is $x = 4.3$.
