Multiplying a vector by a scalar means to multiply each coordinate of the vector by said scalar.
So, we must multiply both entries by 7:

Answer:
c = bx/(x+1)
Step-by-step explanation:
Add cx to get c-terms together, and divide by the coefficient of c.
bx = cx + c
bx = c(x +1) . . . . factor out c
bx/(x +1) = c
A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
Answer
The answer is negative 14.
Step-by-step explanation:
When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.
