Answer:
Answer:Let's solve your equation step-by-step.
Step 1:
13x+8−5x=5x−5x
8x+8=0
Step 2: Subtract 8 from both sides.
8x+8−8=0−8
8x=−8
Step 3: Divide both sides by 8.
8x
8
=
−8

Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405
