Answer:
1a. x=1/2 1b. x= 4
Step-by-step explanation:
1a. 30x= 16- 2x
(add 2x to both sides)
32x= 16
(divide both sides by 16)
x= 1/2
1b. 2(3x-5)=2x+6
(distribute the 2)
6x-10=2x+6
(add 10 to both sides)
6x=2x + 16
(subtract 2x from both sides)
4x= 16
(divide both sides by 4)
x=4
Answer:
5/(3x+2) = 7/(5x-2)
<=>5*(5x-2) = 7*(3x+2) (x is not equal to -3/2 or 2/5)
<=> 25x -10 = 21x +14 (x is not equal to -3/2 or 2/5)
<=> 4x = 24 (x is not equal to -3/2 or 2/5)
<=> x = 6 (valid)
Answer:
(x-8)(x-2)
Step-by-step explanation:
factors of 16:
1 x 16
2 x 8
4 x 4
i'll select 2 and 8 as values because they can add up to 10
(x-8)(x-2)
i made them both negative so the middle term would be -10 but, when multiplied, would equal positive 16
