A mixed number is an integer--whole number--in front of a fraction. To calculate this, you have to divide the numerator by the denominator and put the remainder over the denominator.
Since 3 goes into 16 wholly 5 <em />times with 1 left over, 16/3 = 5 1/3.

(1) 5x=-2+7y
(2) x-7y=-34
Using the method of substitution:
Isolating x from the equation (2):
(2) x-7y=-34
x-7y+7y=-34+7y
x=7y-34 (3)
Replacing x by 7y-34 in the first equation:
(1) 5x=-2+7y
5(7y-34)=-2+7y
Solving for y:
35y-170=-2+7y
35y-170+170-7y=-2+7y+170-7y
28y=168
28y/28=168/28
y=6
Replacing y by 6 in equation (3)
(3) x=7y-34
x=7(6)-34
x=42-34
x=8
Answer: The solution of the system of equations is: x=8 and y=6
