Transform the equation to isolate x: ax = bx + 1. how is
the value of x related to the difference of a and b?

The value of x is inversely proportional to the difference of a and b.

Step-by-step explanation:

The given expression is

We factor the left hand side to get:

We divide both sides by: a-b

Observe that the difference of a and b is in the denominator.

The whole is of the form:

The value of x is inversely proportional to the difference of a and b.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
