Question

Solve the following simultaneous equation. 2x-3y=10 ; 4x-5y=15​

Answer 1

Answer:

X= -5/2

Y= 5

Step-by-step explanation:

2x+3y= 10---- eqn-1

X= 5- 3/2y

4x-5y=15---- eqn-2

Substituting "X= 5- 3/2y" in eqn-2

4 ( 5- 3/2y) + 5y= 15

y = 5

Substituting the value of y in X= 5- 3/2y

X= 5 - 3/2 (5)

X= -5/2
