Question 978051: form equations for each of the following statement:
1. the length of the rectangle is 7m, more than its breadth and its perimeter is 68m.
Ans: L=7m
w=?
P=68m
P=2(L+B)
68=2(7+W)
68=2x7+2W
68=14+2w
68-14=2w
54=2w
54/2=w
27=w

You can put this solution on YOUR website! , but you CAN start this completely in symbols if you want to, and sometimes doing that way is an excellent way.
using simple substitution;
Divide both sides by 2, just for convenience, since both members are products of 2; --------Use this to evaluate L.
