Answer 1

It looks like you've provided a set of equations involving variables x and y, and you're trying to solve for their values. Let's work through the equations step by step.

Equation 1: $\frac{x}{10} - \frac{y}{5} = 0$ Equation 2: $\frac{5x}{3} + \frac{y}{6} = 7$

First, let's solve Equation 1 for x: $\frac{x}{10} = \frac{y}{5}$ $x = 2y$

Now, substitute this value of x into Equation 2: $\frac{5(2y)}{3} + \frac{y}{6} = 7$ $\frac{10y}{3} + \frac{y}{6} = 7$

To add the fractions on the left side, find a common denominator, which is 6: $\frac{20y}{6} + \frac{y}{6} = 7$ $\frac{21y}{6} = 7$

Now, solve for y: $21y = 42$ $y = 2$

Now that we have the value of y, substitute it back into the equation for x: $x = 2y = 2 \cdot 2 = 4$

So, the solutions for x and y are $x = 4$ and $y = 2$, respectively.
