ax - b = c
Add 'b' to both sides
ax = c + b
Divide both sides by 'a'
x = (c + b) / a

ax - b = c
Add 'b' to each side:
ax = b + c
Divide each side by 'a':
x = (b + c) / a
x = b/(a + c)
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
(a + b + c)3 = a3 + b3 + c3 + 3(a2b + ab2 + b2c + bc2 + ca2 + ac2) + 6abc
49 + c units
a + b + c = 180 b = 3a c = 5a Substituting the values of b and c into the first equation. a + 3a + 5a = 180 or 9a = 180 so that a = 20 then b = 3a = 3*20 = 60 and c = 5a = 5*20 = 100
