wuts the answer for
-12 + 5u= -48
-12 + 5u= -48
add 12 to both sides
5u = -48+12
5u = -36
divide both sides by 5
u = -36/5
-12 + 5u= -48
-12 + 12 + 5u = -48 + 12
5u = -36
u = -7.2
Check it out:
-12 + (-36) = -48
-48 = -48
To find the value of u in the equation -12 + 5u = -48, we need to isolate the variable u. Here's how to do it step by step:
1. Start with the equation: -12 + 5u = -48.
2. Our goal is to isolate the variable u, so we want to get rid of the -12 on the left side of the equation. To do this, we need to add 12 to both sides of the equation.
-12 + 12 + 5u = -48 + 12
This simplifies to: 5u = -36.
3. Now, we have the equation 5u = -36. To solve for u, we need to get u by itself. Since 5 is multiplied by u, we need to divide both sides of the equation by 5.
(5u)/5 = (-36)/5
Simplifying, we get: u = -36/5.
4. The answer is u = -36/5, which can also be expressed as a decimal or a mixed number, if necessary.
Therefore, the solution to the equation -12 + 5u = -48 is u = -36/5.
