a-3(5a+4)+7(3a-1)=-43?

a-3(5a+4)+7(3a-1)=-43

a - (15a + 12) + (21a - 7) = -43
a - 15a - 12 + 21a - 7 = -43
(a - 15a + 21a) + (-12 - 7) = -43
7a - 19 = -43
7a - 19 + 19 = -43 + 19
7a = -24
a = -24/7

Already replied so i will take the bonus. i'm the MS guy who mentioned the Cardinals. they're the main generic group up right here interior the northwestern area of the state (the Memphis metro area). yet statewide the Braves, and helpful the Astros, are greater generic. we've countless erroneous human beings in this state. i'm stunned there are greater purple Sox followers properly removed from Boston than the different group has followers far removed from their domicile city. additionally, 12 followers in manhattan, yet no Mets votes yet? it extremely is rather fantastic.

a - 15a - 12 + 21a - 7 = - 43
7a = - 43 + 19
7a = - 24
a = - 24/7

a - 3(5a + 4) + 7(3a - 1) = -43
a - 3*5a - 3*4 + 7*3a - 7*1 = -43
a - 15a - 12 + 21a - 7 = -43
-14a + 21a = -43 + 12 + 7
7a = -24
a = -24/7

yip they are right! i checked :)

a - 3(5a + 4) + 7(3a - 1) = -43

a - 15a - 12 + 21a - 7 = -43

7a - 19 = -43

7a = -43 + 19

7a = -24

a = -24/7

a - 15a -12 +21a -7 = -43
7a -19 = -43
7a = -24
a= -24/7

Is that true ?
