Answer:
Step-by-step explanation:
2x + 5y = 3 ----- (i)
5x - 3y = 4 ----- (ii)
To eliminate you have to make the constant part of any one variable the same.
(i) * 5,
10x + 25y = 15 -----(iii)
(ii) * 2,
10x - 6y = 8 -----(iv)
(iii) - (iv),
31y = 7
y = 7 / 31
Substituting value of y in (i),
2x + 5 * 7 / 31 = 3
2x + 35 / 31 = 3
2x = 3 - 35 / 31
2x = 58 / 31
x = 58 / 62
= 29 / 31
