2/3x + 1/3x - 6 = 1
Group like terms (x):
2/3x + 1/3x = X (because 2/3 + 1/3 = 1)
Rewrite equation with like terms grouped:
x -6 = 1
Get X alone by transposing 6 onto the other side. When its move over its sign will change. Since its a negative number it'll become positive :
x -6 = 1
x = 1 + 6
(1 + 6 = 7)
Therefore X = 7

2/3 x + 1/3x -6 = 1
2/3 x + 1/3x = 7
(2/3+1/3)x = 7
3/3 x = 7
x=7

2/3x+1/3x-6= 1x
equation.
1x= 1+6
add the fractions and bring -6 to the right side of the equation, switch the sign that comes before it.... -6 becomes +6
1x= 7
SOLVE. 1x is the same as simply X
x=7
to check answer, Substitute the answer for X: 2/3(7)+1/3(7)-6=1
: 14/3+7/3-6=1
: 4.67+2.3-6=1
: 7-6=1

X=7 because 2/3 + 1/3 = 1, so it's X-6=1, then add 6 to buth sides of the equals sign and you get X=7

2/3 x + 1/3x -6 = 1
x-6=1
x=7

since 2/3x +1/3x=(1+2)/3x=1/x
so we can get 1/x-6=1 both sides of the equation plus 6,
1/x -6+6=1+6 so 1/x=7 ,then we can get x=1/7

(1) 2/3 x + 1/3x -6 = 1
(2) 2/3x + 1/3x=7
(3) 3/3x = 7
or x=7
