Set up the proportion. That's what similar gives you the right to do.
(12 + 3) / 4x = 12 / (3x + 1) Cross multiply
15 * (3x + 1) = 12 * 4x Remove the brackets
45x + 15 = 48x Subtract 45x from both sides.
15 = 48x - 45x
15 = 3x
x = 5
4b - 24 + 19 = 4b - (-24 + 19) = 4b - 5
Answer: 14-7-2=? is the expression.
The equation can be rewritten as: Log(x*(x+5))=Log=(6x+12)
so x(x+5)=6x+12
x^2+5x=6x+12
x^2-x-12=0
(x+3)(x-4)=0
x=-3 or x=4
x cannot be negative here, so x=4 is the only solution
