3x - 5(3x - 7) = 2(x + 9) + 45
multiply multiply
3x -15x +35 = 2x+18+45
subtract add
-14x = 28
divide the value
x= -2
solution.

3x -5(3x-7) = 2(x+9) + 45
Multiply -5(3x-7) & 2(x+9) u will get:
3x -15x + 35 = 2x+18 + 45
Bring all the x an L.H.S. & numerals on R.H.S. u get:
3x-15x-2x = 18+45-35
-14x = 28
x=28/-14
= -2
therefore, x = -2

3x-5(3x-7)=2(x+9)+45
=>3x-15x+35=2x+18+45
=>-12x-2x=63-35
=>-14x=28
=>x= -2(on dividing by -14)

3x - 5(3x - 7) = 2(x + 9) + 45
3x -15x +35 = 2x+18+45
3x -15x - 2x = 18 +45 -35
-14x = 28
x = -2

3x - 5(3x - 7) = 2(x + 9) + 45
3x - (15x - 35) = 2x + 18 + 45
3x - 15x + 35 = 2x + 63
- 12x + 35 = 2x + 63
- 12x + 35 - 2x = 2x + 63 - 2x
- 14x + 35 = 63
- 14x + 35 - 35 = 63 - 35
- 14x = 28
- 14x / - 14 = 28/ - 14
x = 28 / - 14
x = - 2
