Answer:
I believe this is pathgorean theorem, which I did at the beginning of alegbra last year. It is basically finding the missing side of a triangle. (Trust me some of the easiest stuff you do all year) Below are my notes from last year. I hope it helps! Good Luck!!!
Step-by-step explanation:
Given two sides
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
It would cross the y-axis at 2 and it would cross the x-axis at -2
Explanation- x is the horizontal line and the y is the vertical line. Basically whichever number the line crosses on the x-axis line or the y-axis line would be your answer.
Hope this helps(:
First, you want to even out each side.

You need to inverse -q to +q and add to both sides to get

Now you need to do the oppisite of add to 11 which is subtract it from both sides.
