You just add them :)
2x+7x+3y-3y=-5+9
3y and -3y is 0 which means this equals to 9x=4, so B
Answer:
x = 22/25
Step-by-step explanation:
Given
2 1/5 x
---------- = -----------
10 4
Using cross products
2 1/5 * 4 = x*10
Change 2 1/5 to an improper fraction
2 1/5 =(5*2+1)/5 = 11/5
11/5 *4 = 10x
44/5 =10x
Multiply each side by 1/10 to isolate x
44/5 *1/10 = 10x * 1/10
44/50 = x
Divide top and bottom by 2
22/25 = x

when you're finding slope with two given point you choose the second point of Y subtract the first point of Y. Second point of X subtract first point of X
slope is the change of Y over the Change of X
(3,9) is the second ordered pair so that will be you x2 and y2 because the point is after (0,3)
equation for slope: y2-y1/x2-x1
what you do is
9-3 = 6
3-0=3
6/3 if you simplify it it is 2.
the slope is 2
plug your numbers into the equation and isolate b which is the y intercept
