Question

Solve the following quadratic equation for all values of x in simplest form.
20+ 2x= 28

Answer 1

x = 4

Explanation:

To solve, we need to isolate x.

Start by moving the 20 to the other side by subtracting it from both sides.

2x = 8

Since x is being multiplied by 2, we need to divide both sides by 2 to move it to the other side.

x = 4
