Answer:
Step-by-step explanation:
That means that the given expressions are equal.
100 - 2.5x = 100 + 2.5(5 - x)
100 - 2.5x = 100 + 12.5 - 2.5x
There is no solution to this.
For this case we have to represent the following expression algebraically:
"10 less than x is -45"
So:
10 less than x is represented as: 
Then, the complete expression is represented as:

Adding 10 to both sides of the equation:

Thus, the value of the variable is

How are we supposed to draw a diagram for you? do you want me to explain to you how to answer the question?
Answer:
x = 14
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, hence
4x + 14 + 2x + 15 + 5x - 3 = 180
11x + 26 = 180 ( subtract 26 from both sides )
11x = 154 ( divide both sides by 11 )
x = 14
