−2y−10=6
(1 point)
y=
To solve the equation, we need to isolate the variable y.
First, let's simplify the equation by adding 10 to both sides:
-2y - 10 + 10 = 6 + 10
This simplifies to:
-2y = 16
Next, let's get rid of the coefficient -2 by dividing both sides of the equation by -2:
(-2y) / (-2) = 16 / (-2)
This simplifies to:
y = -8
Therefore, the solution to the equation is y = -8.

25x+4=10
(1 point)
x=
To solve the equation, we need to isolate the variable x.
First, let's simplify the equation by subtracting 4 from both sides:
25x + 4 - 4 = 10 - 4
This simplifies to:
25x = 6
Next, let's get rid of the coefficient 25 by dividing both sides of the equation by 25:
(25x) / 25 = 6 / 25
This simplifies to:
x = 6/25
Therefore, the solution to the equation is x = 6/25.

2/5x+4=10
(1 point)
x=
To solve the equation, we need to isolate the variable x.
First, let's simplify the equation by subtracting 4 from both sides:
2/5x + 4 - 4 = 10 - 4
This simplifies to:
2/5x = 6
Next, let's get rid of the coefficient 2/5 by multiplying both sides of the equation by 5/2 (the reciprocal of 2/5):
(2/5x) * (5/2) = 6 * (5/2)
This simplifies to:
x = 15/2
Therefore, the solution to the equation is x = 15/2.
thats incorrect
Apologies for the mistake. Let's solve the equation correctly.
We begin by subtracting 4 from both sides of the equation:
2/5x + 4 - 4 = 10 - 4
This simplifies to:
2/5x = 6
Next, to isolate x, we multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:
(2/5x) * (5/2) = 6 * (5/2)
This simplifies to:
x = 6 * (5/2) / (2/5)
Next, to simplify this expression, we can multiply the numerator and denominator of the right side by the reciprocal of 2/5, which is 5/2:
x = (6*5/2) * (5/2)
This simplifies to:
x = 30/4 * 5/2
Multiplying the numerators together and the denominators together:
x = 150/8
This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:
x = 75/4
Therefore, the solution to the equation is x = 75/4.
