Step-by-step explanation:

Step 1: Define

11(4 - 6y) + 5(13y + 1) = 9

Step 2: Solve for y

1. Distribute:                              44 - 66y + 65y + 5 = 9
2. Combine like terms:             -y + 49 = 9
3. Isolate y term:                       -y = -40
4. Isolate y:                                y = 40

Step 3: Check

Plug in y into the original equation to verify it's a solution.

1. Substitute in y:                    11(4 - 6(40)) + 5(13(40) + 1) = 9
2. Multiply:                               11(4 - 240) + 5(520 + 1) = 9
3. Subtract/Add:                      11(-236) + 5(521) = 9
4. Multiply:                               -2596 + 2605 = 9
5. Add:                                     9 = 9

Here we see that 9 does indeed equal 9.

∴ y = 40 is the solution to the equation.

Answer 2

Answer:

Y = 40

Step-by-step explanation:

44 - 66y + 65y + 5 = 9

49 - y = 9

-y = -40

y = 40
