Answer 1

3(y-5)=-13
3y-15=-13
3y=-13+15
3y=2
y=2/3

Answer 2

Finding the Value of the Variable

To find the value of the variable u when the expression 3(u-5) equals -13, we can use algebraic manipulation to solve for u.

Algebraic Manipulation

We can start by setting up the equation: 3(u-5) = -13

Next, we can distribute the 3: 3u - 15 = -13

Then, we can isolate the variable u by adding 15 to both sides of the equation: 3u = 2 + 15

Finally, we can solve for u by dividing both sides by 3: u = 17 / 3

The value of the variable u when the expression 3(u-5) equals -13 is 17 / 3.
