4x-y+7=0
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
4x - 5 + 2x = 376x - 5 = 376x = 37 + 56x = 42x = 42 / 6x = 7
If: 4x+3x = 35Then: 7x = 35So: x = 35/7 => x = 5
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
4x + 7 - 8x = 17-4x + 7 = 17-4x = 24x = -6
The given expression can be simplified to: 4x -16
Yes, but the solution is imaginary if you have learned that 4x^2 + 7 = 5 4x^2 = -2 x^2 = -1/2 x = +/-0.707i where i = square root of -1
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
4x - 7 = 5 + 7x x = -4
4x+7-8x=17-4x+7=17-4x=10x = -5/2
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
This would simplify as 4x-5
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
