Question

solve by elimination method 3x+5y=25. 7x+6y=30​

Answer 1

Answer:

x = 0 , y = 5

Step-by-step explanation:

3x+5y=25 * 7 => 21x+ 35y = 175 ( 1 )

7x+6y=30 * 3 => 21x+18y = 90 ( 2 )

Subtracting 1 and 2 we get

17y = 85

y = 5

Substituting y in eq 1

3x+5y = 25

3x + 25 = 25

x = 0

Hope this helps!!
