Answer 1

Answer:

Answer: X=2. Step-by-step explanation: X=2. 7x+5=19. 7x=19-5. 7x=14.

Answer 2

Answer:

3x−5y−19=0...(1)

−7x+3y+1=0....(2)

Let us use elimination method to solve the given system of equations.

Multiply (1) by 3 and (2) by 5. And add both the equations.

−26x=52

9x−15y=57−35x+15y=−5

x=

−26

52

=−2

Substitute the value of x in equation (1), we have

3×(−2)−5y=19⇒−6−5y=19

y=−5

Hence x=−2 and y=−5

⇒x=−2,y=−5
