To solve the system of equations −4x + 6y = 38 and x − 5y = −20, we can use the method of substitution.
Step 1: Solve one equation for one variable. Let's solve the second equation x − 5y = −20 for x:
x = 5y - 20
Step 2: Substitute the expression for x in the first equation:
-4(5y - 20) + 6y = 38
Step 3: Simplify and solve for y:
-20y + 80 + 6y = 38
-14y + 80 = 38
-14y = -42
y = -3
Step 4: Substitute the value of y into the equation x = 5y - 20:
x = 5(-3) - 20
x = -15 - 20
x = -35
Therefore, the solution to the system of equations is (-35, -3).

To solve the system of equations:
1. Start by using one of the equations to solve for one variable in terms of the other. Let's solve equation (2) for x:
x - 5y = -20
x = 5y - 20
2. Now substitute this expression for x into the other equation (equation 1) and solve for y:
-4(5y - 20) + 6y = 38
-20y + 80 + 6y = 38
-14y = -42
y = 3
3. Substitute the value of y back into either equation to solve for x. Let's use equation (2):
x - 5(3) = -20
x - 15 = -20
x = -5
Therefore, the solution to the system of equations is (x, y) = (-5, 3).
