48
-4a = 48 a = -12
42 over 48 equals 8 OR 42/48 = 8 is an incorrect mathematical equation.
39 + 12w = 1039 -10 = -12w29 = -12ww = -12/29 = -0.413
If you mean 6 times 8 then it equals 48
-48 -16 = 20 First add -48 and -16, which = -64, which indicates that this is not an equation, because both sides are not equal. -64 ≠20
t - 17 = 48 The first step is to move the -17 to the right side of the equation and end up with: t = 48 + 17. (When you switch sides, the sign changes) To solve the equation: t = 65
4(w^2 + 3w + 1)
This is the algebraic equation 2(x) + (x)2 = 48 And the equation x2 + 2x -48 = 0 has the solution (x-6)(x+8) = 0 So the number is either 6 or -8.

Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
