Q:
# if a + b + C = -1 and x + y + z = -8, what is -8z -8x + 5a + 5c - 8y + 5b

Accepted Solution

A:

Answer:59Step-by-step explanation:a + b + C = -1 x + y + z = -8We want 5a so multiply the first equation by 55(a + b + c) = -1*55a+5b+5c = -5We want -8x so multiply the second equation by -8 -8(x + y + z) = -8*-8-8x-8y-8x = 64Add these equations together5a+5b+5c = -5-8x-8y-8x = 64----------------------------8x -8y-8x+5a+5b+5c = 59Rearrange the order-8z -8x + 5a + 5c - 8y + 5b = 59
