Question

Solve this equation
7x-5y = 300
3x-2y = 300
Find the value of x and y
Pls solve step by step

Answer 1

Answer:

value of x= 900

value of y= 1200

Step-by-step explanation:

7x-5y= 300 ...... eqn(1)

3x-2y= 300 ...... eqn(2)

eqn (1)×2 - eqn (2)×5;

we get,

{2(7x-5y)}-{5(3x-2y)}= (300×2)-(300×5)

14x-10y-15x+10y= 600-1500

x= 900

put the value of x in eqn(2);

we have,

3×900-2y= 300

2y= 2700-300= 2400

y= 2400/2= 1200

Hope it helps!
