y
7
It is 2y.
It is an expression in two variable: it is NOT an equation. There is no standard form for expressions.
A coefficient is the number in front of a variable. For example, consider the expression '2y' y is the variable 2 is the coefficient
It is a quadratic expression which when factored is (2y+3)(y+5)
When you see "y times 2," it means you are multiplying the variable y by the number 2. So the expression "y times 2" can be written as 2y. This is a simple algebraic expression where the coefficient of y is 2.
Combine like terms. 6x - 2y +7.
A mathematical phrase with at least one variable is an expression that includes numbers, operations, and one or more letters representing unknown values. For example, the expression ( 3x + 5 ) contains the variable ( x ) and represents a relationship where ( x ) can take on different values. Another example is ( 2y - 7 = 0 ), which includes the variable ( y ) and represents an equation.
