Hello there!
4(2x + 1) - 3 = -3(x - 4)
We need to distribute both sides
(4)(2x) + (4)(1) - 3 = (-3)(x) + (-3)(-4)
8x + 4 - 3 = -3x + 12
8x + 1 = -3x + 12
Now subtract 1 from both sides
8x + 1 - 1 = -3x + 12 - 1
8x = -3x + 11
Add 3x to both sides
8x + 3x = -3x + 11 - 3x
11x = 11
x = 11/11
x = 1
I hope this helps~!
Good luck with your career!
