7y + 8 = 57, then 2y =
y = 7;
2y = 14.
To find the value of 2y, we need to isolate the variable y by performing some algebraic operations.
Given the equation 7y + 8 = 57, we want to move the constant term 8 to the other side of the equation to isolate the y term.
Subtracting 8 from both sides of the equation:
7y + 8 - 8 = 57 - 8
This simplifies to:
7y = 49
Now, to solve for y, we need to get rid of the coefficient 7 in front of y. To do this, we divide both sides of the equation by 7:
(7y) / 7 = 49 / 7
Simplifying further:
y = 7
Now, to find 2y, we simply substitute the value we obtained for y into the expression 2y:
2y = 2 * 7
This gives us:
2y = 14
Therefore, the value of 2y is 14.
