\frac{x}{2} = \frac{40}{16}

To find our solution (x), we multiply both sides by 2. Then we get the following:

\frac{x}{2} \times 2 = \frac{40}{16} \times 2
x = \frac{40}{16} \times \frac{2}{1}
x = \frac{80}{16} = 5

Therefore the answer is x = 5

Solve x
d1i1m1o1n [39]

Step-by-step explanation:

x^{2} - 4x - 7 = 0

First, let's move the 7 to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:

x^{2} - 4x = 7

From here, since the coefficient of the x term is -4, we know the square will be (x - 2) (since -2 it's half of -4).

To complete this square, we will need to add (-2)^{2} to both sides of the equation:

x^{2} - 4x + (-2)^2 = 7 + ^{-2}

x^{2} - 4x + 4 = 7 + 4

(x - 2)^{2} = 11

Now we can take the square root of both sides to figure out the solutions to x:

x - 2 = \pm \sqrt{11}

x = 2 \pm \sqrt{11}
