Answer 2

To solve the given system of equations using the method of substitution, we'll start by solving the first equation for x in terms of y and then substitute it into the second equation. Let's begin:

Given: x = 2y ...(Equation 1) And: x + 3y = 10 ...(Equation 2)

Step 1: Solve Equation 1 for x From Equation 1, we have x = 2y.

Step 2: Substitute x = 2y into Equation 2 Substituting x = 2y into Equation 2, we get: 2y + 3y = 10 5y = 10 y = 10/5 y = 2

Step 3: Substitute the value of y back into Equation 1 to find x Using Equation 1, when y = 2, we have: x = 2y x = 2 * 2 x = 4

Therefore, the solution to the given system of equations is: x = 4 and y = 2.
