Answer:
6. x=11/25
7. x= 1/10
8. x = 1/4
9. x = -1
10. x=7
11. x=11/50
12. x=41/100
Step-by-step explanation:
6.add 2 to both sides , -18x=8, divide by -18 , simplify fraction to 11/25
7. 20x-4=-2. Add 4 to both sides. 20x=2. divide by 20. x=1/10
8. Distribute to get 8x-4=-2. add 4 to both sides. 8x=2. divide by 8. x=1/4
9. Distribute to get -6x+-8=-2. add 8 to both sides. -6x=6 divide by -6. x=-1
10. distribute to get -x-3=-10. add 3 to both sides -x=-7, x=7
11. 20x-4-2x+2=-6 , add like terms, 18x-2=-6 add 2 to both sides, 18x=-4 , divide by 18 . x=11/50
12. add like terms . -24x+4=-6, subtract 4 , -24x=-10 . divide by -24 x= 41/100
