3(2 + y)
It is: 3y-6
Yes, the expression (3y - 6 - 6) simplifies to (3y - 12), which is not equivalent to (3y). Therefore, (3y - 6 - 6) is not equivalent to (3y).
The expression "x plus y - 2" can be written as ( x + y - 2 ). The expression "3x plus 3y - 6" simplifies to ( 3(x + y - 2) ). Therefore, both expressions represent the same relationship, as the second expression is simply three times the first. Thus, ( 3x + 3y - 6 ) is equivalent to multiplying ( x + y - 2 ) by 3.

To factor the expression (4x + 6y), you first identify the greatest common factor (GCF) of the coefficients 4 and 6, which is 2. Then, you can factor out the GCF from the expression: [4x + 6y = 2(2x + 3y).] Thus, the factored form is (2(2x + 3y)).
5x + 3y + 6 is an algebraic expression. It is not an equation (or inequality) and so cannot be solved. In any case, one linear equation with two variables cannot be solved.
The expression 3x + 3y is a linear combination of two variables, x and y, with coefficients 3. The answer to this expression depends on the specific values of x and y. If x = 2 and y = 4, then the answer would be 3(2) + 3(4) = 6 + 12 = 18. In general, the answer to 3x + 3y is 3 times the sum of x and y.
(y + 6)(y - 3)
-4(7x-3y-z)-(-6)(9x-z+2)
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
2x-11
The GCF is 6.
