____________
3x=1
x=1/3
I feel like i did this wrong
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,
<u>x = 1</u>
<u>y = -7/2</u>
