Answer:
x = 14
Step-by-step explanation:
let the number be x.
now,
Given that,
4x + 10 = 5x - 4
moving all x terms to the LHS and the constants to the RHS
4x - 5x = -4 - 10
-x = -14
dividing both sides by -1
<u>x = 14</u>

2(L+W) = 34
L + W = 17
.
L*W = 52
L = 2W+5
2L + 2W = 34
L - 2W = 5
--------------- add
3L = 39
L = 13
