Answer 1

Solving the System of Equations

To solve the system of equations:

4x + 3y = 5
5x - y = -13

we can use the method of substitution or elimination. Let's use the method of substitution.

First, let's solve one equation for one variable and substitute it into the other equation. Let's solve the second equation for y:

5x - y = -13
y = 5x + 13

Now, substitute this expression for y in the first equation:

4x + 3(5x + 13) = 5
4x + 15x + 39 = 5
19x + 39 = 5
19x = -34
x = -34/19

Now, substitute the value of x back into the second equation to find y:

5(-34/19) - y = -13
-170/19 - y = -13
y = -170/19 + 247/19
y = 77/19

Therefore, the solution to the system of equations is (x, y) = (-34/19, 77/19).
