<span><span>K = k + 13</span><span>78</span></span> Cross multiply: K * 8 = 7 * k + 13 Simplifying K * 8 = 7 * k + 13 Reorder the terms for easier multiplication: 8K = 7 * k + 13 Reorder the terms: 8K = 7 * 13 + k 8K = 13 * 7 + k * 7 8K = 91 + 7k Solving 8K = 91 + 7k Solving for variable 'K'. Move all terms containing K to the left, all other terms to the right. Divide each side by '8'. K = 11.375 + 0.875k Simplifying K = 11.375 + 0.875k

If a+b+c=8 and x+y=7 what is -8y-2c-2b-8x-2a
sergey [27]

Answer:

-40

Step-by-step explanation:

Try rearranging and factoring -8y-2c-2b-8x-2a:

This is equal to -8(x + y) -2(a + b + c).

Since x + y = 7, we have:

                            -8(7) -2(a + b + c)

and since a + b + c = 8, we end up with:

                             -56 - 2(8), or

                               -56 - 16    = -40
