I done this in my mind
here it is:
3 2 x + 10 - 5 x = 5 3 6
or, 3 2 x - 5 x = 5 3 6 - 10
or, 1 5 1 0 x − 3 x = − 2 1 0
or, 35x =-210
or, x= -6

3 2 x + 1 0 − 5 x = 5 3 6
The L C D is 1 5 , multiply both sides of the equation by 1 5 .
( 3 2 x + 1 0 − 5 x ) ( 1 5 ) = ( 5 3 6 ) ( 1 5 )
1 0 x + 1 5 0 − 3 x = 1 0 8
Combine like terms.
7 x + 1 5 0 = 1 0 8
Transpose 1 5 0 to the other side of the equation.
7 x = 1 0 8 − 1 5 0
Combine like terms.
7 x = − 4 2
Divide both sides 7 .
x = − 6
Verify the solution by substitution.
1 0 ( − 6 ) + 1 5 0 − 3 ( − 6 ) = 1 0 8
− 6 0 + 1 5 0 + 1 8 = 1 0 8
1 0 8 = 1 0 8 The statement is true. Therefore, -6 is the solution.
