B = 1500 + R
B = B - 175
R = R + 175
Then B = 3 * R
B - 175 = 3 ( R + 175)
= 3R + 525
B = 3R + 700
Now apply B = 1500 + R , as mentioned above
Ie . 1500 + R = 3 R + 700
2 R = 800
R = 400
Then B = 1500 + 400 = 1900
Total = 1900 + 400 = 2300
B = B - 175
R = R + 175
Then B = 3 * R
B - 175 = 3 ( R + 175)
= 3R + 525
B = 3R + 700
Now apply B = 1500 + R , as mentioned above
Ie . 1500 + R = 3 R + 700
2 R = 800
R = 400
Then B = 1500 + 400 = 1900
Total = 1900 + 400 = 2300
