4x+3+27=90
4x+30=90
90-30 =60
60/4 =15
X=15
$9000, 25x50 is the WxL shown here. 25m is half the length of 50m which is twice the length of the width, 25m. 2L+2W= 2(50)+2(25)=150m total needed. 150m total fencingx$60 per M of fencing= $9000
Here we go ~
According to given figure,
The given equations are;
2x-y=8......(i)
3x+y=17......(ii)
Adding equation (i) and (ii), we get
5x=25 ( as +y and -y is canceled out during addition)
Hence x=5
Now
Substituting the value of x in equation (i)
2x5-y=8
10-y=8
Hence y=2
