Answer 2

To solve the equation $(x + 10) \cdot 3.5 + x \cdot 3.5 = 490$, you can follow these steps:

1. Distribute the constants on the left side of the equation:

$(3.5x + 35) + (3.5x) = 490$

2. Combine like terms on the left side:

$3.5x + 3.5x + 35 = 490$

3. Add the two 3.5x terms together:

$7x + 35 = 490$

4. Now, subtract 35 from both sides to isolate the term with x:

$7x = 490 - 35$

$7x = 455$

5. Finally, divide both sides by 7 to solve for x:

$x = \frac{455}{7}$

Now, let's simplify the fraction:

$x = 65$

So, the solution to the equation is $x = 65$.
