(x-3)/4 =(y-7)/2 if 11x=13y
Answers
Answer:
The naswer will be:
x = 143 / 9;
y = 121 / 9;
Step-by-step explanation:
The equation given;
⇒ (x-3)/4 = (y-7)/2 ;
Given things ;
11x = 13y; (i)
Now, simplify the given equation;
⇒ (x-3)/2 = (y-7) ;
⇒ x - 3 = 2y - 14 ;
⇒ x = 2y - 11 ; (ii)
Now, from equation (i);
x = 13y / 11 ;
Now put this value in equation (ii);
⇒ 13y / 11 = 2y - 11 ;
⇒ 13y = 22y - 121 ;
⇒ 22y - 13y = 121 ;
⇒ 9y = 121;
y = 121 / 9;
Now, x will be;
put the value of y in equation (i);
11x = 13 (121/9) ;
x = {13 (121/9)} / 11;
= (13 * 11) / 9;
= 143 / 9;
That's all.
