Question

2(x + 7y - 5) - 3 (x + y)​

Answer 1

2(x + 7y - 5) - 3 (x + y) = 2х + 14у - 10 - 3х - 3у = - х + 11у - 10

Answer 2

To simplify the expression 2(x + 7y - 5) - 3(x + y), you can distribute the constants 2 and -3 into the parentheses and then combine like terms:

2(x + 7y - 5) - 3(x + y)

= 2x + 14y - 10 - 3x - 3y

Now, combine like terms by adding or subtracting coefficients of the same variable:

(2x - 3x) + (14y - 3y) - 10

= -x + 11y - 10

So, the simplified expression is -x + 11y - 10.
