-2y - 10 = 15
FOOLS
(10 points)
y =
-12.5
To solve the linear equation -2y - 10 = 15, we need to isolate the variable y.
Let's start by adding 10 to both sides of the equation to get rid of the -10 term:
-2y - 10 + 10 = 15 + 10
Simplifying, we have:
-2y = 25
Next, we want to get y by itself, so we divide both sides of the equation by -2:
-2y / -2 = 25 / -2
Simplifying further:
y = -12.5
Therefore, the solution to the linear equation -2y - 10 = 15 is y = -12.5.
To solve the linear equation -2y - 10 = 15, we need to isolate the variable 'y'.
Step 1: Start by moving the constant term (-10) to the other side of the equation.
-2y - 10 + 10 = 15 + 10
This simplifies to:
-2y = 25
Step 2: Divide both sides of the equation by the coefficient of 'y', which is -2.
-2y / -2 = 25 / -2
This simplifies to:
y = -25/2
Therefore, the solution to the equation -2y - 10 = 15 is y = -25/2.
