L-5=w and (L)(W)=24
From there you can use elimination or substitution to solve... You should get
L=8
W=3
15 * 0 = -36 + a is your first expression
Solve the equation to find.
Add 36
(15 * 0) + 36 = a
0 + 36 = a
36 = a
Your second equation
24 * 8 * 0 = 36 - b
Add 36
(24 * 8 * 0) + 36 = b
36 = b
36 is the answer
8/45 is already in simplest form because it has NO common denominator to divide both, the numerator and the denominator with. So no, 8/45 cannot be simplified. <span />
1. Add the 1 to the 23 because if it's a negative you add and if it's positive you subtract and because you need x by itself
2. divide -6 to 24
3. x=-4
