Ineed with 4x + 5y = 11 i am confused

Simplifying 4x + 5y = 11
 
Solving 4x + 5y = 11

 Solving for variable 'x'.

 Move all terms containing x to the left, all other terms to the right.

 Add '-5y' to each side of the equation. 4x + 5y + -5y = 11 + -5y

 Combine like terms: 5y + -5y = 0 4x + 0 = 11 + -5y 4x = 11 + -5y

 Divide each side by '4'. x = 2.75 + -1.25y

 Simplifying x = 2.75 + -1.25y

256 Coins

Step-by-step explanation:

On the first day, Jada starts with one coin, so all you have to do here is multiply it by 2.

Day 1: 2 coins

Day 2: 2 x 2 = 4 coins

Day 3: 4 x 2 = 8 coins

Day 4: 8 x 2 = 16 coins

Day 5: 16 x 2 = 32 coins

Day 6: 32 x 2 = 64 coins

Day 7: 64 x 2 = 128 coins

Day 8: 128 x 2 = 256 coins
