i dont have much time to go through all the work but i can tell you that since its a 90 degree angle, your equation would be 90=15x-2+7x+4. Once you get the value of X plug that into each of the equations. For example if your x value was 2 you would do 15(2)-2. Thats just an example.
109 numbers hope this helps :)
Answer:
21-14a
Step-by-step explanation:
You have to distribute the (2/3) into the (15-21a) then add it to the 11. So after distributing the (2/3) into the (15-21a) is (10-14a). Then add that to the 11
Answer:
-15
Step-by-step explanation:
Given:
Simply plug in and see if the statement is true. If not, isolate x.
Test for truth:
Isolate x in original equation:
- -14+7=x+8
- -14+7-8=x
- -7-8=x
- -15=x
