thank u so much♥️
HETA1208, I think The ending part is wrong
hmm
ask google
The numbers are x & y
x/y = 3/5
5x = 3y
X = 3y/5
X+10 = 5/7
Y+10
7x+70 = 5y+50
7x – 5y = 50 – 70
7(3y/5) – 5y = -20
21y/5 – 5y = -20
21y – 25y = -20
5
-4y = -20 x 5
Y = -20 x 5
-4
Y = 5 x 5 =25
x/y = 3/5
5x = 3y
X = 3y/5
X+10 = 5/7
Y+10
7x+70 = 5y+50
7x – 5y = 50 – 70
7(3y/5) – 5y = -20
21y/5 – 5y = -20
21y – 25y = -20
5
-4y = -20 x 5
Y = -20 x 5
-4
Y = 5 x 5 =25
5 is the denominator for both 21 and -25 . -4 comes under -20 x 5. I couldn't draw the lines in comments. but I believe answer is 25
yup
the ans is 15 and 25
