Answer 1

90у+138+155-55у
35у+293

Answer 2

90y+138+155-55y = 35y+293

Answer 3

To solve the expression, you need to perform the operations following the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's solve the expression step-by-step:

1. First, perform the operations within the parentheses: 6(15y + 23) + 5(31 - 11y)

2. Distribute the numbers outside the parentheses to the terms inside: 6 * 15y + 6 * 23 + 5 * 31 - 5 * 11y

3. Perform the multiplications: 90y + 138 + 155 - 55y

4. Combine like terms (terms with the same variable, 'y'): (90y - 55y) + (138 + 155)

5. Perform the subtractions: 35y + 293

The simplified expression is: 35y + 293
