Answer:

Step-by-step explanation:

x²-3x-28=0

x²-7x+4x-28=0

x(x-7)+4(x-7)=0

(x-7)(x+4)=0

x=7,-4

4-2/3(4x-9)=11 solve for x
djyliett [7]

x= -3/8

here's how you solve it!

first distribute the -2/3 into the parentheses and you'll get:

4-8/3x+6=11

Then add 4 and 6 together

10-8/3x=11

Then multiply the equation by 3

30-8x=33

Then move the constant to the other side and change the sign

-8x=33-30

Subtract 30 from 33

-8x=3

Then divide both sides by -8

x=-3/8

Then you are left with your answer:

x= -3/8

Hope this helps! :3
