Question

One step equations
3-u=5

Answer 1

• u = -2

Step-by-step explanation:

To solve the one-step equation 3 - u = 5, We need to isolate the variable u.

Start with the equation:

• 3 - u = 5.

To isolate u, subtract 3 from both sides of the equation to get u by itself on one side:

• 3 - u - 3 = 5 - 3.

Simplify both sides:

• -u = 2

Now, to solve for u, multiply both sides by -1 to get the value of u:

• -1 × (-u) = -1 × 2,

• u = -2

So, the solution to the equation 3 - u = 5 is u = -2.

Answer 2

Answer: u = -2

Step-by-step explanation: In this problem, we want to get u by itself on one side of the equation.

To do this, we start by subtracting 3 from both sides of the equation.

That gives us -u = 2.

Now, we divide both sides by -1 and u = -2.
