solve for u.\n2.5 - 0.5u = 0.5u - 1 + 0.75u\nu =

Explanation:

Step1: Combine like terms on the right side

Combine (0.5u) and (0.75u) on the right - hand side of the equation. (2.5−0.5u=(0.5 + 0.75)u-1) (2.5−0.5u = 1.25u-1)

Step2: Add (0.5u) to both sides

To get all the (u) terms on one side, add (0.5u) to both sides of the equation. (2.5−0.5u+0.5u=1.25u + 0.5u-1) (2.5=1.75u-1)

Step3: Add 1 to both sides

To isolate the term with (u), add 1 to both sides of the equation. (2.5 + 1=1.75u-1 + 1) (3.5 = 1.75u)

Step4: Divide both sides by 1.75

To solve for (u), divide both sides of the equation by 1.75. (u=\frac{3.5}{1.75}) (u = 2)
