4 ^ ( x - 1 ) = 4 ^ x / 4 ^ 1 = 4 ^ x / 4 4 ^ x - 4 ^ ( x - 1 ) = 24 4 ^ x - 4 ^ x / 4 = 24 4 * 4 ^ x / 4 - 4 ^ x / 4 = 24 3 * 4 ^ x / 4 = 24 Multiply both sides by 4 3 * 4 ^ x = 96 Divide both sides by 3 4 ^ x = 32 x * log ( 4 ) = log ( 32 ) Divide both sides by log ( 4 ) x =...

A + B + B = 35 A + 2 B = 35 B + B + C = 25 2 B + C = 25 A + B + B + B + C = 55 A + 3 B + C = 55 You have 3 equations : A + 2 B = 35 2 B + C = 25 A + 3 B + C = 55 A + 2 B = 35 Subtract A to both sides A + 2 B - A = 35 - A 2 B = 35 - A 2 B + C = 25 Subtract C to both sides 2 B +...
