In π = 7x - 2y we first isolate y by adding 7x on both sides.
This gives us π + 7x = -2y. Divide 2 on both sides, then we are left with:
y =
Answer:
0.15590200
Step-by-step explanation:
Answer:
If that was x square .. Then here is your answer...
A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3
