In the equation 4x - 2y = 8, what is the value of y when x = 2?
Steps
Concepts
Step 1: Start with the equation 4x - 2y = 8.
Step 2: Substitute the value of x (which is 2) into the equation.
Step 3: Replace x in the equation: 4(2) - 2y = 8.
Step 4: Calculate 4(2) which equals 8, so the equation becomes 8 - 2y = 8.
Step 5: To isolate -2y, subtract 8 from both sides: 8 - 2y - 8 = 8 - 8.
Step 6: This simplifies to -2y = 0.
Step 7: To find y, divide both sides by -2: y = 0 / -2.
Step 8: This simplifies to y = 0.
