Final answer:
To solve for u in the equation 8=8v-6v, combine the v terms, isolate v, substitute v back into the equation to solve for u.
Step-by-step explanation:
To solve for u in the equation 8 = 8v - 6v, we can start by combining the v terms on the right side of the equation. This gives us 2v. Therefore, the equation becomes 8 = 2v.
To solve for u, we need to isolate v. Since v is multiplied by 2, we can divide both sides of the equation by 2 to cancel out the 2. This gives us 4 = v.
Now that we know v is 4, we can substitute it back into the original equation to solve for u. Substituting 4 for v in 8 = 8v - 6v, we get 8 = 8(4) - 6(4). Simplifying, we have 8 = 32 - 24, which gives us 8 = 8.
Therefore, the value of u is 8.
