Answer:
The answer to your question is below
Step-by-step explanation:
-4x² + 9y² + 32x + 36y - 64 = 0
-4x² + 32x + 9y² + 36y = 64
-4(x² + 8x ) + 9(y² + 4x ) = 64 Factor coefficients
-4(x² + 8x + 4²) + 9(y² + 4x + 2²) = 64 - 64 + 36 Complete trinomials
-4(x + 4)² + 9(y + 2)² = 36 Factor trinomials
Divide by 36
Simplify

Answer:
5:1
Step-by-step explanation:
divide eatch side
26 / 8 = 3.25;
14 / 4 = 3.50;
The mistake is obvious !
We need to isolate b on it own by rearrange:
3a+2b=c
-3a -3a
2b=c-3a
/2 /2
Ans: b=
