Answer:
The point of intersection is (2,5)
Explanation:
To get the point of intersection, we would need to solve the two equations simultaneously. This is because, the point of intersection satisfies both equations.
The first given equation is:
25x + 10y = 100 ..........> equation I
The second given equation is:
10x + 20y = 120
Divide all terms by 10 to simplify, this would given us:
x + 2y = 12
This equation can be rewritten as:
x = 12 - 2y ...........> equation II
Substitute with equation I in equation II and solve for y as follows:
25x + 10y = 100
25(12-2y) + 10y = 100
300 - 50y + 10y = 100
300 - 40y = 100
300 - 100 = 40y
40y = 200
y = 200 / 40
y = 5
Substitute with y in equation II to get x as follows:
x = 12 - 2y
x = 12 - 2(5)
x = 12 - 10
x = 2
Based on the above, the solution to the system of equations which also represents the point of intersection between the two lines would be (2,5)
Hope this helps :)

Answer:
17/9 or 1 8/9 if you are looking for a mixed fraction
Step-by-step explanation:
1 7/9 + 4/36
16/9 + 4/36
Multiply 16/9 by 4/4 to get the same denominator as 4/36
64/36 + 4/36
68/36 = 17/9 = 1 8/9
