3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
5x + 8 = 2x + 7 5x - 2x = -8 + 7 3x = -1 x = -1/3 (5 x -1/3 + 8 = 6 1/3; 2 x -1/3 + 7 = 6 1/3; QED)
5x - 3 + 2x + 7 = ?7x + 5 = ?
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
5x + 8 = 2x + 7 5x - 2x = -8 + 7 3x = -1 x = -1/3 (5 x -1/3 + 8 = 6 1/3; 2 x -1/3 + 7 = 6 1/3; QED)
5x - 3 + 2x + 7 = ?7x + 5 = ?
8x-7 plus 2x equals 6 plus 5x plus 2?
-6x+3 = -7-5x 7+3 = 6x-5x 10=x
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
If you mean: 3+5x+7 = 70 then the value of x is 12
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
