You can put this solution on YOUR website!

4x%2B5y=11
y=3x-13+ you can take this value of y and substitute it in first expresion, so you can find x
4x+%2B+5%283x+-+13%29+=+11
4x+%2B+15x+-+65+=+11
19x+=+11+%2B+65
19x+=+76
x+=+76%2F19
x+=+4
now, go back to
y+=+3x+-+13
and find y
y+=+3%2A4+-+13
y+=+12+-+13
y+=+-1
