4x + 7 - 8x = 17-4x + 7 = 17-4x = 24x = -6
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.

The given expression can be simplified to: 4x -16
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
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
x=2/7
what is the product of ( 4x-7) (4x+7)
3
It's an equation. Specifically, a linear equation in ' x '.Here's the solution for ' x ':4x + 7 = -3 - x5x + 7 = -35x = -10x = -2
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
4x + 7 = 0 4x = -7 4x/4= -7/4 X = -7/4
