x = 5 and y = -2
Step-by-step explanation:
Two equations are given and we have to solve those two equations by elimination process.
The equations are
⇒ 5y = 3x - 25
⇒ 3x - 5y = 25 ......... (1) and
x + 3y = - 1
⇒ 3x + 9y = -3 ........... (2)
Now, eliminate x from equations (1) and (2) by {(2) - (1)}
14y = - 28
⇒ y = - 2
Now, from equation (1) we get, 3x = 25 + 5y = 15
⇒ x = 5
Therefore, the solution of the given equations are x = 5 and y = -2. (Answer)
