8x + 7
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5x - 17 = x + 7 4x - 17 = 7 4x = 24 x = 6 Check it. 30 - 17 = 13 It checks.
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
If: 3x-7 = 5x+13 Then: x = -10
8x + 7
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5x - 17 = x + 7 4x - 17 = 7 4x = 24 x = 6 Check it. 30 - 17 = 13 It checks.
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
If: 3x-7 = 5x+13 Then: x = -10
5m + 7 - 2m - 1 = 3m + 6
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x - 3 + 2x + 7 = ?7x + 5 = ?
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
5x+7
