solve problem 2/3a + 1 =9?

2/3 a +1 =9 <==>
2/3a = 8 <==>
a=3*8/2 <==>
a=12

if you mean 2/ (3a+1) =9 <==>
2= 27a +9 <===>
27a = -7 <===> a = - 7/27

2/3a + 1 = 9
2/3a = 9 - 1
2/3a = 8
a = 8/(2/3)
a = 8(3/2)
a = 12

Answer: a = 12

Proof:
(2/3[12]) + 1 = 9
8 + 1 = 9
9 = 9

2/3a + 1 = 9
2/3a = 9 - 1
2/3a = 8
2 = 3a(8)
2 = 24a
24a = 2
a = 2/24
a = 1/12

8 - 5(4 - 3x) = 2(4 - x) - 8x 8 - 20 + 15x = 8 - 2x - 8x -12 + 15x = 8 -10x 10x + 15x = 8 +12 25x = 20 x = 20/25 = 4/5 (a+2)(a^2-3a+7) =a^3 - 3a^2 + 7a + 2a^2 - 6a + 14 =a^3 - a^2 + a + 14 (3x^2 y)(-2xy)^3 = 3(-2)^3 * x^5 * y^4 = -24 * x^5 * y^4 sqrt(4x-2) = sqrt(3x+9) sq. the two facets 4x-2 = 3x+9 4x - 3x = 9 + 2 x = 11 sqrt(x^2-y^2) isn't x -y. think that it extremely is. sqrt(x^2 - y^2) = x - y sq. the two facets x^2 - y^2 = (x - y)^2 x^2 - y^2 = x^2 - 2xy + y^2 0 = 2y^2 - 2xy 0 = y(y-x) purely actual if y=0 or y=x.

Should be shown as :-
(2/3) a + 1 = 9
(2/3) a = 8
2a = 24
a = 12

If its 2/(3a) +1 = 9;
then,

2/3a +1 = 9
2/3a = 8
2 = 24a
a = 1/12

If its (2/3)a +1 = 9,
then,

2/3a + 1 = 9
2/3a = 8
2a = 24
a = 12

2/3a+1=9
2/3a+1-1=9-1
2/3a=8
2a=3 x 8
2a=24
a=24/2=12

2/3a+1=9
2/3a=8
2/3a*3/2=8*3/2
a=24/2=12

a = 12
2/3(12) + 1 = 9
8 + 1 = 9
9 = 9

(2/3)a + 1 = 9
2/3a = 9-1
2/3a = 8
a = 8*(3/2)
a = 12
