First, move all terms containing a to the left, all other terms to the right.
Add '2b' to each side of the equation.4a + -2b + 2b = 16 + 2b
Combine like terms: -2b + 2b = 04a + 0 = 16 + 2b4a = 16 + 2b
Divide each side by '4'.a = 4 + 0.5b
Answer
= 4 + 0.5b
Happy studying ^-^
Answer:
Step-by-step explanation:
8b-4b+8-3=4b+5
4b=-5

Given:
The train has 6 passenger cars
Each car has 4 columns
And 1 column hold 50 passengers
So, total of seats will be = 6 * 4 * 50 = 1200
Now, there are 25 empty seats,
therefore the correct equation will be :
Number of seats per car: 4 × 50 = 200
Total number of seats: 200 × 6 = 1,200
Number of passengers: 1,200 − 25 = p
