no its not a solution

The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
2x + 3 = 72x = 4x = 2
{-1,-2}
Yes, x = 2 is the solution.
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
Yes. It is THE solution.
4x plus 7 plus 3x equals 19 plus xx = 2
4x + 2 + 6 = 2 4x + 8 = 2 4x = -6 x = -6/4 = -3/2
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
