Step-by-step explanation:
All the variables on the right are being multiplied together then the whole mess is being divided by 2. Let's get rid of the 2 first. The undoing of division is multiplication, so we will begin by multiplying both sides by 2 to get
Next we will move the m. The undoing of multiplication is division. So we divide both sides by m to get
The undoing of a square is to take the square root, so we will do that to both sides giving us, finally
First, distribute 2 to the (x+3) to get:
21 = 2x+6
subtract 6 from both sides to get:
15 = 2x
Finally, we divide both sides by 2 to simplify x to:
x = 7.5 (OR) x =
