The equation x2 + 6x = 7 can be rewritten as x2 + 6x - 7 = 0. This quadratic equation can be solved using the quadratic formula or factoring. Both methods will result in 2 solutions, one positive and one negative. However, only the negative solution of -1 will satisfy the equation given.

Option A (-1) is the correct solution but in the positive form, which does not satisfy the equation.

Option C (1/2) is the inverse of option B (-1/2), which would result in a positive solution that does not satisfy the equation.

Option D (1) is also a positive solution that does not satisfy the equation. Therefore, option B (-1/2) is the only correct solution that satisfies the given equation.
