4x+13 = 21 4x = 21-13 4x = 8 x = 2
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
ln(4x)=13 4x=e^13 x=(e^13)/4

3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
x = 2
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
4x + 3 = 16 Therefore, 4x = 13 x = 13/4 Therefore, x = 3.25
x=4
5x - 4x = 13 - 3 ie x = 10
