For this case we have to:
x: Let the variable representing the unknown number
We algebraically rewrite the given expression:
Twice a number plus 10, is represented as:
Three times that number less 4. is represented as:

Thus, the complete expression is:

Subtracting 3x from both sides of the inequality:

Subtracting 10 from both sides of the inequality:

Equal signs are added and the same sign is placed:

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

The solution is given by all values of "x" less than 14.
Answer:

Answer:
x = -5
Step-by-step explanation:
Combine them like terms,then you subtract 4 from both sides,and then Simplify
