Solve for x,
5(ax-1)=(bx+4)
5(ax-1)=(bx+4)
-
5(ax - 1) = bx + 4
5ax - 5 = bx + 4
5ax - bx = 9
x(5a - b) = 9
x = 9 / (5a - b)
5ax - 5 = bx + 4
5ax - bx = 9
x(5a - b) = 9
x = 9 / (5a - b)
-
5ax - 5 = bx + 4
5ax - bx = 4 + 5
(5a - b) x = 9
X = 9 / (5a-b)
5ax - bx = 4 + 5
(5a - b) x = 9
X = 9 / (5a-b)
-
x = 9/(a-b)
