The value of x so that the equation based on a and b has a solution is x = -7/5
What is an equation?
An equation is about two expressions, either arithmetic or algebraic, that are related with a "=" sign that indicates equality of expressions.
Equations can be graphed, they are used to model many problems and theories.
As we can see, we have the following equation:
(a + 2)b + 13 = 5x
and we have the values of the coefficients a and b, and these are:
We substitute these values in the equation:
(a + 2)b + 13 = 5x
(18 + 2)-1 + 13 = 5x We solve the equation
(20)-1 +13 = 5x
-20 + 13 = 5x
5x = -7
x = -7/5
