To find the value of "x", you need to isolate/get the variable "x" by itself in the equation:
4x - 1 = 6 Add 1 on both sides
4x - 1 + 1 = 6 + 1
4x = 7 Divide 4 on both sides to get "x" by itself
[tex]\frac{4x}{4} =\frac{7}{4}[/tex]
[tex]x=\frac{7}{4}[/tex]
Now that you know the value of x, you can find 24x:
24x Substitute/plug in 7/4 into "x" since x = 7/4
[tex]24(\frac{7}{4})=\frac{(24)7}{4}[/tex]
42
