Can you help me with algebra?
i have 9 equations to answer.
5. -3x=12
6. 4/5x=20
7. 9x+7=8x
8. 7x-3+8=6x
9. -2(x+3)=3(x-7)
10. 2/3-x+5x=1/2+x
11. -0.2(3x-8)=1.6+2x
12. 3(x-5)=2(x+5)+x
13. 4(3-6x)=-2(x+5)
i got
5. x=-4
6. x=25
7. x=-7
8. -z=5
9. 5 2/5
10. -2/3
11. -3.2=2.6x
12. -25=0
13. 11/13

Number 5 is right. Just solve for x (leave x alone on one side of the equation).
Number 6 is right. Just solve for x.
Number 7 is right.
Number 8. Instead of -z = 5, say z= -5.
Number 9. x=3 Simplify the equation to -2x – 6= 3x – 21.
Number 10. x= -1/18 3x= -1/6
Number 11. x=0 Simplify it to -.6x +1.6=1.6 +2x
Number 12. -15 = 10 Undefined (no answer could solve this)
Number 13. x=1 Simplify to 12- 24x= -2x – 10
p.s. LA TotiJoe, #6 is truly 25. Checking 1/25 would give you 4/125 (1/25 x 4/5). 25 x 4/5 would be 100/5 or 20.

Number 6 is 1/25 not 25. When you cross multiply, you get 100x=4 or x=4/100 or 1/25.
