What is x and how do i figure it out 4x = 8 + 2x

x = 4

Let's solve your equation step-by-step.

4x=8+2x

Step 1: Simplify both sides of the equation.

4x=2x+8

Step 2: Subtract 2x from both sides.

4x−2x=2x+8−2x

2x=8

Step 3: Divide both sides by 2.

2x/2=8/2

x=4

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
