Step-by-step explanation:
y = x - 4
Step 1: Flip the equation.
x − 4 = y
Step 2: Add 4 to both sides.
x − 4 + 4 = y + 4
Answer is: x = y + 4
-4x - 6y = -16
Step 1: Add 6y to both sides.
−4x − 6y + 6y = −16 + 6y
−4x = 6y − 16
Step 2: Divide both sides by -4.
−4x
/−4 = 6y−16
/−4
Answer: x = −3/2 y + 4
