First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7

2x + 3 = 72x = 4x = 2
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2

4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
4x + 7 - 8x = 17-4x + 7 = 17-4x = 24x = -6
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
If you mean: 3x -7 +4x = 28 then the value of x works out as 5

If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
3x+7=4x 7=4x-3x 7=x
It's an equation. Specifically, a linear equation in ' x '.Here's the solution for ' x ':4x + 7 = -3 - x5x + 7 = -35x = -10x = -2
