What you have to do is figure out how many half inches you need to have to figure out how many half inches equal 5 yards. Therefore if there are 12 inches in a foot, then that would be 24 half inches. So..... three feet equal 1 yards. So multiply 3 by 24. 3x24=72 so you would need 72 half inches
Easiest method solving 2 unknowns is Substitution.
So there will normally be 2(ormore)equations given.
Say
X+Y= a
bX=cY + d
a b c d are numbers they give
So first we rearrange the first equation
X = a - Y
No we substitute this into the 2nd equation so that we can get Y
since we know X = a-Y,
b(a-Y) = cY + d
we rearrange and we can find Y for this, it is just Y and numbers
hence finding Y, we sub the value for Y into X = a-Y and we get X also .
