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
