3x+5y=1025
x+5=275
x = 270
3(270) + 5y = 1025
810 + 5y = 1025
5y = 215
y = 43
Please show me the steps and solve.

ah, andra, are you sure you did not mean:
x + 5 y = 275 ???????
x + 5 y = 275 ???????
Actuaally, it was a word problem and that's the equation I got out of it. Here is the word problem.
Students sold 275 tickets for a fundraiser at school. Some tickets are for the children and cost $3 while the rest are adult tickets that cost $5. If the total value of all the tickets sold was $1025, how many of each ticket were sold? To help you solve this problem, write a linear equation.

3 c + 5 a = 1025
c + a = 275
so c = (275 -a)
3 (275-a) + 5 a = 1025
825 - 3 a + 5 a = 1025
2 a = 100
a = 100 and c = 275-100 = 175
c + a = 275
so c = (275 -a)
3 (275-a) + 5 a = 1025
825 - 3 a + 5 a = 1025
2 a = 100
a = 100 and c = 275-100 = 175
