The value of X in the equation that allows a solution with the values of "a" and "b" is x = 16
What are the equations?
An equation is the equality that has mathematical expressions on both sides of it, they can be functions, polynomials or others, there are no limits for them.
Equations can be graphed, just like a function.
We write the given equation
b = 3x + 4a
and we have the values of the coefficients a and b, and these are:
We substitute these values in the equation:
b = 3x + 4a
(12) = 3x + 4(-9) :::: We solve the equation
12 = 3x -36
3x = 12 + 36
3x = 48
x = 48/3
x = 16
