hope it helped you:)
Answer:
x=-4.5 or -9/2
Step-by-step explanation:
3(6+8x)=3(6x+1)
18+24x=18x+3
6x=-15
x=-15/6
x=-9/2
Answer:
Yes
Step-by-step explanation:
she scored 18 points, then minus 6. She would have 12. She made it to the next level
-10y + 9x = - 9....A
10y + 5x = - 5.....B
You should see right away that -10y and 10y cancel out.
We are left with
14x = -14
x = -14/14
x = -1
Plug x = -1 into EITHER equation A or B to find y.
I will use equation A.
-10y + 9(-1) = - 9
-10y - 9 = - 9
-10y = - 9 + 9
- 10y = 0
y = 0/-10
y = 0
Done!
