Evaluate the Expression: 8(x-7)+4(6-2y) with x=8 and y=5

To solve this problem, we'll follow these steps:

• Step 1: Substitute the given values into the expression.
• Step 2: Simplify the expression step-by-step.
• Step 3: Evaluate and find the final result.

Now, let's work through each step:

Step 1: Substitute $x = 8$ and $y = 5$ into the expression:
$8(x-7) + 4(6-2y) \rightarrow 8(8-7) + 4(6-2 \times 5)$.

Step 2: Simplify the expression:
- First, evaluate $8(8-7)$. Since $(8-7) = 1$, we have:
$8 \times 1 = 8$.

- Next, evaluate $4(6-2 \times 5)$. Compute $2 \times 5 = 10$, so $6 - 10 = -4$.
Therefore, $4 \times (-4) = -16$.

Step 3: Combine the terms:
$8 + (-16) = 8 - 16 = -8$.

Therefore, the solution to the problem is $-8$.
