Answer:
This system of equations can be solved using substitution or elimination methods.
Using substitution, we can solve for one of the variables in one of the equations and substitute that expression into the other equation.
Solving for x in the second equation:
x + 3y = 1
x = 1 - 3y
Substituting this expression for x into the first equation:
-4(1 - 3y) - 15y = -10
Expanding and solving for y:
-4 + 12y - 15y = -10
12y - 4 = -10
12y = -6
y = -1/2
Now that we know y = -1/2, we can substitute this value back into the expression for x:
x = 1 - 3(-1/2) = 1 + 3/2 = 7/2
So the solution to the system of equations is (7/2, -1/2).
Checking the solution in both equations:
-4(7/2) - 15(-1/2) = -4(7/2) + 15/
