6x-1=4x+6
subtracting 4x from each side
2x-1=6
adding 1 to each side
2x=7
divide by 2
x=7/2 or 3.5
check: 6(7/2) -1 =4(7/2)+6
21-1 =14+6
20=20 correct
it would be known as a mixed fraction....?
Answer:
f(x) = (x - 10) (x + 10)
Step-by-step explanation:
The equation looks like the difference of squares so 5 and 20 are out
-10 x -10 = 100
-10 x 10 = - 100
so (x - 10) (x + 10)
