Answer:
The solution of the given equations is (-3,2)
Step-by-step explanation:
<u>Step:1</u>
The Given equations are 2 x+3 y=0 .......(1)
x+2 y-1 =0.........(2)
<u>Step 2:-</u>
Solving<u> </u>both equations by using substitution method
multiply equation (2) with number '2' ,
2 x+4 y-2=0.......(3)
subtracting the equations (1) and (3) and cancelled 'x' terms
we get 

<u>Step 3:</u>-
substitute y= 2 in equation (1) we get




<u>Final answer</u>:-
The solution of the given equations is (-3,2)
Answer:
50 is the answer that I got.
Answer:

Step-by-step explanation:
First you can notice the y-intercept is 4. Then notice how the y value increases exponentially based on the x valie, making it non-linear, rather a porabla.
6-4.7=1.3
7.3-6=1.3
8.6-7.3=1.3

d=1.3
-------------------------------------------------
a1=4.7
a2=a1+(n-1)d
6=4.7+1d→d=1.3
X+n-8
I think that's right.
I hope this helps.
