(45 - 2x)-(4x+10)=
(15-14x)
15
5
9​

Answer 1

Answer:

(45-2x)/15 – (4x+10)/5 = (15-14x)/9 By rearranging (45-2x)/15 – (4x+10)/5 – (15-14x)/9 = 0 By taking LCM for 15, 5 and 9 which is 45 ((45-2x)3 – (4x+10)9 – (15-14x)5)/45 = 0 (135 – 6x – 36x – 90 – 75 + 70x)/45 = 0 (28x – 30)/45 = 0 By cross-multiplying 28x – 30 = 0 28x = 30 x = 30/28 = 15/14 Let us verify the given equation now, (45-2x)/15 – (4x+10)/5 = (15-14x)/9 By substituting the value of ‘x’ we get, (45-2(15/14))/15 – (4(15/14) + 10)/5 = (15 – 14(15/14))/9 (45- 15/7)/15 – (30/7 + 10)/5 = (15-15)/9 300/105 – 100/35 = 0 (300-300)/105 = 0 0 = 0 Hence, the given equation is verified.Read more on Sarthaks.com - https://www.sarthaks.com/664767/solve-the-equationand-also-check-your-results-45-2x-15-4x-10-5-15-14x-9

Answer 2

Answer:

-5/2

Explanation:

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

=> 45 - 2x - 4x - 10 = 15 - 14x

=> 35 - 6x = 15 - 14x

=> 14x - 6x = 15 - 35

=> 8x = - 20

=> x = -20/8

x = -5/2
