Answer 2

To find the solutions to the system of equations, you need to solve for the values of x and y that satisfy both equations simultaneously. Let's proceed step by step.

Given system of equations:

1. x + 2y = 0.3 ...........(Equation 1)
2. x = -y + 0.5 ...........(Equation 2)

To solve the system, we can use the substitution method. From Equation 2, we can express x in terms of y:

x = -y + 0.5 ...........(Equation 2)

Now, substitute this value of x into Equation 1:

(-y + 0.5) + 2y = 0.3

Combine like terms:

-y + 2y + 0.5 = 0.3

Simplify:

y + 0.5 = 0.3

Now, isolate y:

y = 0.3 - 0.5

y = -0.2

Now that we have found the value of y, we can find the corresponding value of x using Equation 2:

x = -(-0.2) + 0.5

x = 0.2 + 0.5

x = 0.7

So, the solutions to the system of equations are x = 0.7 and y = -0.2.
