We are given the following:

=======================

Solve for x.


-4+5x-7=10+3x-2x

=======================

In order to determine the value of x, we need to isolate the variable by dividing each side by factors that do not contain the variable.

Hence regarding this particular situation, our solutions would be as follows:

  • Exact Form:
    x=(21)/(4)
  • Decimal Form:
    x=5.25

Depending on whether you are looking for the exact form of decimal form, I listed both for you just in case. Hope this helps! Good luck!

We can begin by rewriting the equation:

-4 + 5x - 7 = 10 + 3x - 2x

1. Combine like terms

5x - 11 = x + 10

2. Subtract 1 from both sides

4x - 11 = 10

3. Add 11 to both sides

4x = 21

4. Divide both sides by 4

x = 5 1/4 OR 5.25

There are no answer choices given, but the answer is 5 1/4 or 5.25 in decimal form.
