The answer to this is 10.
You need to have variables one one side and constants on the other. ax - ax + by = c - ax
by = c - ax
by/b = (c - ax)/b
y = (c - ax)/b
Answer:
2x + 70 = 110
x = 20
Step-by-step explanation:
180-110 = 70
70 + 20 + y = 180
y =90
A^2+b^2=(a+b) (a-b)
Let a^2=x^2 then a^2= x^2
Let b^2=63 them b^2= 64
b=8
Answer: (x+8) (x-8)
