2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
Depending on how the problem is written. 2x + 3 - 5x + 10 -3x + 13 ■ Or... 2x + 3 - (5x + 10) -3x - 7 ■ I think you want the second answer.
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)
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
Depending on how the problem is written. 2x + 3 - 5x + 10 -3x + 13 ■ Or... 2x + 3 - (5x + 10) -3x - 7 ■ I think you want the second answer.
-2x-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)
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
5x+7
If there are no equals you can simplify this by collecting all the x values together and use the addition property of signed numbers. 2x+4x-5x+x=2x; 4+3=7. 2x+7 is the simplified statement.
8x-7 plus 2x equals 6 plus 5x plus 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+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
