Answer:
always have a solution
Step-by-step explanation:
A linear equation in standard form is given by:
Ax + By = C, where A,B, C are real numbers and A,B is not equal to zero.
Two linear equations with equations Ax + By = C and Dx + Ey = F
Therefore the first equation becomes: (A/B)x + y = C/B and the second equation becomes (D/E)x + y = F/E ]
Both equations are said have a solution if A/B ≠ D/E, they have no solution if A/B = D/E and they have infinite solutions if A/B = D/E, C/B = F/E.
Given that:
when a > b
ax + y = 8
bx + y = 5
Since a ≠ b, but a > b, the system has a solution
Add the ratios together: 2 + 3 +4 = 9
Divide the total tips by 9:
77.40 / 9 = 8.60
Multiply each portion of the ratio by 8.60:
2 x 8.60 = 17.20
3 x 8.60 = 25.80
4 x 8.60 = 34.40
The ratios are in order of the people:
Paul got 17.20
Colin got 25.80
Brian got 34.40
Brian got 34.40 - 17.20 = 17.20 more than Paul

If you mean 12x by “1and2x”. it’s 9x - 5y = 0.
If it’s 1x and 2x it’s y= 2/5x^2 -3/5x, x
16 because 48/3 = 16 and we know that he started with 50 chocolates then distributed 3 times the number of friends present. This is written as 50 - 3x. We also know that there were 2 chocolates left so -3x = 2 - 50 which when simplified is x = 48/3 which equals 16.
