Answer:
The solution is at (-0.5,0.5).
Step-by-step explanation:
I graphed both equations on the graph below to show you where the solution of the system is.
Answer:
(8 * x) + 2x = 60
8x + 2x = 60
10x = 60
/10 /10
x = 6
8 is a constant that is being multiplied by an unknown number which we will name x. It is then being added to two times the unknown number(x), so we multiply x by 2, which is 2x. The final product will be 60, so in the equation it'll then equal 60.
We consider "a number" to be a variable that withholds an unknown value, which is x (or any other variable you prefer).
You would need more details like the y values or something. Rate of change is slope though if that helps you enough to figure it out
Your answer should be 1/6 because you are dividing thing by the number.
