(divide fencing per cost (8) from cost (12.40) to get how much it costs per foot (1.55) then multiply it by how much feet you need (36))
Easy and simple:::::
4(2x-3)=3+8x-11
Solve for x, i.e separate x in one side and the other terms in the other side
8x - 12 = 8x - 8
8x - 8x = -8 + 12
This equation has all real number as solutions.....infinite number of solutions
