____________

3x=1

x=1/3

I feel like i did this wrong

Answer 2

Multiply the second row by 5

5x - 4y = 19

5x - 10y = 40

Subtract the 2nd row from the 1st row

6y = -21

Solve for y in the above equation

y = -7/2

Substitute y = -7/2 into any of the above equations. Let's pick the first one; 5x - 4y = 19

5x - 4 × -7/2 = 19

Solve for x in the equation above

x = 1

Therefore,

x = 1

y = -7/2
