There are 4 equal slices because 25 to 25 to 25 to 25 =100
solve the equation for X by finding a,b, and c of the quadratic then applying the quadratic formula.
I guess you want to find the values of x & y. If so:
7x+2y=24
8x+2y=30
1) multiply the 1st equation by (-1)==> -7x-2y=-24
2) Now add -7x-2y=-24 to 8x+2y=30 ==> x + 0y = 6 ==> x = 6
3) replace x by 6 in any of te two equation & you will find y= - 9
