**Jen**, Sunday, November 21, 2010 at 11:25am.25q+.05n=10.75 (1)

q+n=95 (2)

Multiply (2) by -.25 to cancel the q's

.25q+.05n=10.75 (1)

-.25q-.25n=-23.75 (3)

-.2n=-13

Divide both sides by -.2

n=65

From (2), q+n=95, q+65=95, q=30

When plugged back into equation 1, it checks. It works in both equations, so this is your solution.
