Answer:
5 wood
Step-by-step explanation:
If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13
Answer:
-1557
Step-by-step explanation:
a+14d=143
a+12d=183
--------------------
2d= -40
d= -20
a=183+240=423
a(100th)= 423+99*-20=423-1980= -1557
