OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
Here is the answer with Steps: 15x - 18 = -2x - 5 15x = -2x + 13 17x = 13 x = 13/17 x ~ .764705882
13x = 15 - 2 x Solve for x 1. Get the x's on one side. Add 2x to each side. 13x + 2x = 15 - 2x + 2x This is the same as 15x = 15 2. Get x by itself. Divide each side by 15. 15x/15 = 15/15 x = 1
With great difficulty in the absence of an equality sign.
2x+3 = 7 2x = 7-3 2x = 4 x = 2
I think you mean 6x2-15x-21 2x2-5x-7 2x2-7x+2x-7 x(2x-7)+1(2x-7) (x+1)(2x-7)
15x-20y= 7 5y-3 +10x

2x 5 -7 = 3
13x = 15 - 2 x Solve for x 1. Get the x's on one side. Add 2x to each side. 13x + 2x = 15 - 2x + 2x This is the same as 15x = 15 2. Get x by itself. Divide each side by 15. 15x/15 = 15/15 x = 1

2x+3 = 7 2x = 7-3 2x = 4 x = 2
you just add 6x+9x to get 15x then minus 25 from 18 to get -7 thus the answer will be 15x-7
Thee of them which are 14x, -x and 2x = 15x
If 2X - 87 = 0 Then: 2X = 87 X = 43.5
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
