Well the 4 would have to be distributed into the 12 and m so you would have 9m+48-4m.
Then you would have to take 9m and subtract 4m from it so it would be 5m+48 and that would be your answer!!! 
Hope it helps

Solve for x if sqrt (3x-8) + 1 = sqrt (x+5)
In-s [12.5K]

The solution of x in the given expression \mathbf{\sqrt{(3x-8)}+1 = \sqrt{(x+5)}} is 4. However, if it is \mathbf{\sqrt{(3x-8)+1} = \sqrt{(x+5)}}, it is 6.

<h3>What is the solution to algebraic expression?</h3>

The solution to the given algebra expression involving surds can be seen in the steps below.

Given that:

\mathbf{\sqrt{(3x-8)}+1 = \sqrt{(x+5)}}

Remove the square roots, we have:

12x - 32 = 4x² - 48x + 144

Solving the quadratic equation at the RHS and equating it to LHS, we have:

x = 11, x = 4

Verifying the solutions by replacing the value of x with the given equation:

  • x = 11 False
  • x = 4 True

Therefore, we can conclude that the value of x = 4

NOTE:

Given that:

\mathbf{\sqrt{(3x-8+1)} = \sqrt{(x+5)}}

Square both sides

3x - 7 = x +5

Solve for x

3x - x = 5 + 7

2x = 12

x = 6
