Question 257380
Let eva = E and elvin, brother, = B.
we have the following equations based on the given information:
(i) E = B + 6
(ii) E + 4 = (1/2)B + 26
multiply (ii) by 2 to get
(iii) 2E + 8 = B + 52
Substitute (i) into (iii) to get
(iv) 2(B + 6) + 8 = B + 52
simplify to get
2B + 12 + 8 = B + 52
B = 32.
E = 38.
