Answer:
A = 3
Step-by-step explanation:
[tex]3a - 10 + 8 + a = 2a + 5a - 11\\[/tex]
Steps:
1) Combine like terms
[tex]4a-2 = 7a-11[/tex]
2) Either subtact 7a from 4a or 4a from 7a. ( I did 7a-4a because so i dont have a negiative in front of my variable)
[tex]-2 = 3a -11[/tex]
3) If u did it like me you add 11 to -2 and add 11 to -11 (which cancel out)
[tex]9=3a[/tex]
4) Divide 3a by 3(which is just a) and 9 divided by 3
[tex]3=a[/tex]
4) Check your answer (just plug in 3 for a and solve. You should get 10=10.)
Hope this helps just let me know if u have any questions about my answer :P
