Math Problem Statement

$$$$ \sqrt{x+3}+x

Solution

The image you uploaded contains the following expression:

x+3+7x=2x5\sqrt{x+3} + \sqrt{7-x} = 2x - 5

To solve for xx, we can proceed as follows:

Step 1: Isolate one of the square root terms

Let's isolate x+3\sqrt{x+3}:

x+3=2x57x\sqrt{x+3} = 2x - 5 - \sqrt{7-x}

Step 2: Square both sides to eliminate the square root

Square both sides to get rid of the square root on the left side:

x+3=(2x57x)2x + 3 = (2x - 5 - \sqrt{7-x})^2

Expand the square on the right-hand side:

x+3=(2x5)22(2x5)7x+(7x)x + 3 = (2x - 5)^2 - 2(2x - 5)\sqrt{7-x} + (7-x)

Step 3: Simplify and solve

This equation is complex due to the presence of the square root on the right-hand side, so it will likely require further manipulation or possibly iterative methods to solve exactly.

Here are some follow-up questions for you:

  1. Would you like to see a step-by-step expansion of the squared term (2x57x)2(2x - 5 - \sqrt{7-x})^2?
  2. Are you interested in exploring methods to simplify or approximate the solution to this equation?
  3. Do you want to discuss alternative methods for solving equations with square roots?
  4. Should I provide examples of similar problems for additional practice?
  5. Do you need clarification on why we square both sides in such problems?

Tip: When solving equations involving square roots, isolating the square root term and then squaring both sides is a common strategy. However, always check for extraneous solutions at the end, as squaring can introduce solutions that don't satisfy the original equation.
