If a = -15, b = 5 and c = -2 a - b - c = -15 - 5 - (-2) = -20 + 2 = -18
-9
Then A = 31, b = 31 and c = 31/15 = 2.066...
ax + b = 15 or ax + b = -15

If a = -15, b = 5 and c = -2 a - b - c = -15 - 5 - (-2) = -20 + 2 = -18
-9
Then A = 31, b = 31 and c = 31/15 = 2.066...
15+b = 23 Subtract 15 from both sides b = 8
ax + b = 15 or ax + b = -15
15
a = 6b = 9a + b = 6 + 9 = 15
b=12
15-b=7.
15 - 12 = 3 B = 15
90% of 45= 90% * 45= 0.9 * 45= 40.5
