The ratio of two integers is 7:12. Their sum is 76. Find the two integers
A = one integer\
B = the other
A + B = 76 → Call this eq1
7A = 12B
A = 12B / 7 →calll this eq2
subtitue eq2 in eq1
12B/7 + B = 76
12B + 7B = 76 x 7
19 B = 76 x 7
B = (76 x 7) / 19
B = 28
Substitute B + 28 to eq 2
A + B = 76 → Call this eq1
A + 28 = 72
In the first part I want to make a correction her in stead of 72 change this to 76
A + 28 = 76
A = 76 - 28
A = 48
