Answer:
x=40/33
Step-by-step explanation:
Let's solve your equation step-by-step.
25(4x−3)−2x=45−x
Step 1: Simplify both sides of the equation.
25(4x−3)−2x=45−x
(25)(4x)+(25)(−3)+−2x=45+−x(Distribute)
100x+−75+−2x=45+−x
(100x+−2x)+(−75)=−x+45(Combine Like Terms)
98x+−75=−x+45
98x−75=−x+45
Step 2: Add x to both sides.
98x−75+x=−x+45+x
99x−75=45
Step 3: Add 75 to both sides.
99x−75+75=45+75
99x=120
Step 4: Divide both sides by 99.
99x
99

Answer:
x=40/33
I believe the answer would be non-proportional
Remember that the sum of tow cubes identity is:

So, to create our expression<span>, containing at least two variables, that can be factored using the sum of two cubes, we just need to replace </span>

and

with tow monomials with a different variable:

and

Lets replace those values in our identity:

Now that we have our expression, lets factor it using the sum of two cubes identity:

To verify if the factored form of our expression (right hand side) is equivalent to the original form (left hand side), we are going to expand the right hand side:




Since both sides of the equation are equal, we can conduce that the factored form of our expression is equivalent to the original expression.
Hope the shown work helps you!!
