(-2 + 0.8) ÷ (1²-1.3) =
(-1.2) ÷ (1-1.3)
(-1.2) ÷ (-0.3)
= 4

300²+400²=500² is your answer
a²<span> + b</span>²<span> = c</span>²
-10.3 + y = 5.2
First, regroup the terms. / Your problem should look like:
Second, add 10.3 to both sides. / Your problem should look like:
Third, add 5.2 + 10.3 to get 15.5 / Your problem should look like:

Answer:
y = 15.5 (D)
