3y-6=20
To solve this equation first what you have to do is isolate the variable and its coefficient(3). So what you have to do is first add 6 to each side of the equation ( remember you have to do the opposite operations.) Then you would be left with 3y=26. Next what you do is divide each side of the equation by the coefficient. Then you will be left with what y equals to.
To solve for y, first, we must isolate the term with y to one side of the equation. We can see that on the left side of the equation, the term with y is 3y, but the left side also has -6 in it. Thus we transfer it on the right, but its sign becomes the opposite (positive in this case):
3y - 6 = 20
3y = 20 + 6
Then we combine the terms on the right side:
3y = 26
To get y alone, we must divide all terms in the equation by the numerical coefficient of y (or the number beside y), which is 3. Thus,
3y / 3 = 26 / 3
y = 26/3 or 8.67

3y-6=20
Add 6 to both sides.
3y = 26
Divide both sides by 3
y = 8 2/3
To solve the equation 3y - 6 = 20, we need to isolate the variable y, which means we want to get y alone on one side of the equation.
Step 1: Start with the equation 3y - 6 = 20.
Step 2: Add 6 to both sides of the equation to get rid of the -6 on the left side: 3y - 6 + 6 = 20 + 6. Simplify: 3y = 26.
Step 3: Divide both sides by 3 to solve for y: (3y)/3 = 26/3. Simplify: y = 26/3 (or 8 2/3 in mixed number form).
Therefore, the solution to the equation 3y - 6 = 20 is y = 26/3 or 8 2/3.
In simple terms: To solve the equation, I added 6 to both sides of the equation to get rid of the -6. Then, I divided both sides by 3 to isolate the variable y.
