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
To solve the inequality (-4x - 7 > 5), first add 7 to both sides to get (-4x > 12). Next, divide both sides by -4, remembering to reverse the inequality sign, resulting in (x < -3). Thus, the solution is (x < -3).
To solve the equation (4x + 17 = 45), first, subtract 17 from both sides to obtain (4x = 28). Next, divide both sides by 4, yielding (x = 7). Thus, the solution is (x = 7).
