5 - 3 ( 4x - 3) + 9x = -7( 2x - 7 ) - 14 5 - 12x + 9 + 9x = -14x + 40 9 - 14 4 - 3x = -14x + 35 -3x = -14x + 31 11x / 11 = 31/11 only undergo in concepts that once a unfavorable is elevated by ability of a unfavorable it is going to become a great. -7 X -7 = 40 9 no longer - 40 9.

4x + 5(7x - 3) = 9( x-5)
=> 4x + 5*7x +5*(-3) = 9*x +9*(-5)
=> 4x+35x-15=9x-45
=>39x-15=9x-45
=>39x-9x-15=9x-9x-45
=>30x-15=-45
=>30x-15+15=-45+15
=>30x=-30
=>30x/30=-30/30
=>x=-1

Expand brackets first and then simplify where necessary:

4x + 35x - 15 = 9x - 45
39x - 15 = 9x - 45

Move the 9x to the other side by subtracting both sides by 9x.

30x - 15 = -45

Move the -15 to the other side by adding 15 to both sides.

30x = -30

Divide both sides by 30 to get x by itself:

x = -1
