Answer:
x = 10/3
x = 3 1/3
(3 whole number, 1/3)
Step-by-step explanation:
To solve for x, we just simplifying the expression.
Be mindful of the signs!
Let's go on now!
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)
Maths is fun !
A cubic function only has 3 solutions at which x = 0, never 4. For example the function y = 
gives the solutions:
x = 0, x = -1 and x = -2
x = 0, x = -1 and x = -2
