3x+y=9 ....(1)
3x-5y=15. ......(2)
-[3x-5y=15]
=> 3x+ y = 9
-3x+5y=-15
..........................
0 +6y=-6
so,y=-1
3x+(-1)=9
3x=10
x=10/3

The initial cost over 4 years?? What are you talking about
Parallel lines add to 180 therefore x is 146
Answer:
Perimeter of the rectangle=Perimeter of the trapezium
2{(3x+4)+(4x)}=2(5x)+(x-3)+(7x-3)
→2(7x+4)=10x+x-3+7x-3
→14x+8=18x-6
→4x=14
→x=7/2
<u>→</u><u>x=3.5</u>
The value of x is <u>3.5 cm</u>
