Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)
Answer:
Hi, there you have to count by 10
or you can just Multiply
5*10=50
Your answer will be 50 :)
Hope this helps :)

The equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.
<h3>What is the equation of a line passing through two given points in a 2-dimensional plane?</h3>
Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

The graph of the picture shows two clear points (4.5. 0) and (0, 9)

Hence, the equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.
