Question

(3x+5y) (7x-6y)
solve them and ​

Answer 1

Answer:

7x+6y=3800 ---- (i)

3x+5y=1750 ---- (ii)

Multiplying (i) by 5 and (ii) by 6, we get

35x+30y=19000 ---- (iii)

$$18x + 30y = 10500$$ ---- (iv)

Subtracting (iv) from (iii), we get

(35x+30y)−(18x+30y)=1900−10500

x=500

put =500 in (ii)

3(500)+5y=1750

y=50

x=500,y=50
