Question

(45-2x)/15-(4x+10)/5=(15-14x)/9

Answer 1

(45-2x)/15 - (4x+10)/5 = (15-14x)/9

(45-2x)/15 - [(4x+10)/5]×3/3 = (15-14x)/9

(45-2x)/15 - [3(4x+10)/15] = (15-14x)/9

(45-2x)/15 - (12x+30)/15 = (15-14x)/9

[(45-2x-12x-30)]/15 = (15-14x)/9

9(15-14x) = 15(15-14x)

135 - 126x = 225 - 210x

-126x+210x = 225-135

84x = 90

x = 90/84

x = 15/14

Hope it helps
