Question

What is the solution to the system of equations below? Y=-1/3x+6 and x=-6

Answer 1

y = -1/3 x + 6 ------------- ( 1 )

x = - 6 ------------------------ (2)

Sub (2) into (1):

y = -1/3 (- 6) + 6

y = 2 + 6

y = 8

Answer: x = - 6 , y = 8

Answer 2

$\left\{\begin{array}{ccc}y=-\frac{1}{3}x+6\\x=-6\end{array}\right\\\text{put the value of x to the first equation}\\\\y=-\dfrac{1}{3}\cdot(-6)+6=2+6=8\\\\\text{Answer:}\ x=-6;\ y=8\to(-6;\ 8)$
