<h3><u>
The value of y is 1.6</u></h3><h3><u>
The value of x is 4.5</u></h3>
By elimination:
2x + 5y = 17
6x - 5y = 19
<em><u>We can add the second equation to the first in order to isolate one variable.</u></em>
(2x + 5y) + (6x - 5y)
8x = 17
<em><u>Because we added the left side, we have to add the right side here as well.</u></em>
17 + 19 = 36
8x = 36
<em><u>Divide both sides by 8</u></em>
x = 4.5
We can plug this value back into the original equation to find the value of y.
2(4.5) + 5y = 17
9 + 5y = 17
<em><u>Subtract 9 from both sides.</u></em>
5y = 8
<em><u>Divide both sides by 5.</u></em>
y = 1.6

Answer:
y=2x-9
Step-by-step explanation:
remember equation of a line: y=mx+b, where m=slope and b= y-intercept
y=mx+b
y=2x+b
we know one point, so we plug it in for x and y
5=2(7)+b
5=14+b
b=-9
so now that we have b, we can write y=2x-9
U subtract 10-y and that will give u how much is X
