Step-by-step explanation:

To solve for x, we just simplifying the expression.

Be mindful of the signs!

x + 7/-3 = 1

Begin by Multiplying all through by -3.

The expression becomes:

(-3 * x) + (7/-3) * -3 = 1 * -3

-3x + 7 = -3

-3x = -3 -7

-3x = -10

Divide both sides by the coefficient of x.

x = -10 / -3

x = 10/3

x = 3   1/3

(3 whole number, 1/3)
