solve the following equation: 6y - 20=2y -4
Add 20 and subtract 2y from both sides.
To solve the equation 6y - 20 = 2y - 4, we need to isolate the variable y. Let's go step by step:
1. Start by getting all terms with y on one side of the equation. To do this, we can subtract 2y from both sides:
6y - 2y - 20 = 2y - 2y - 4
Simplifying the equation gives: 4y - 20 = -4
2. Next, let's isolate the constant term -20. We can do this by adding 20 to both sides of the equation:
4y - 20 + 20 = -4 + 20
Simplifying the equation gives: 4y = 16
3. Finally, we can solve for y by dividing both sides of the equation by 4:
(4y)/4 = 16/4
Simplifying the equation gives: y = 4
Therefore, the solution to the equation 6y - 20 = 2y - 4 is y = 4.
