Answer:
3 and 8
Explanation:
3a + 5b = 49
2b = 5a + 1
then:
2b - 5a = 1 equation 1
-5a + 2b = 1 equation 2
then:
multiplyng by -2.5 the equation 2 and sum to the equation 1:
3a + 5b = 49
12.5a - 5b = -2,5
15.5a + 0 = 46.5
15.5a = 46.5
a = 46.5/15.5
a = 3
2b = 5a + 1
2b = (5*3) + 1
2b = 15 + 1
2b = 16
b = 16/2
b = 8
Check:
3a + 5b = 49
3*3 + 5*8 = 49
9 + 40 = 49
