2x+3y=10
The algebraic expression for twice a number ( n ) increased by 19 is ( 2n + 19 ). This expression represents taking the number ( n ), multiplying it by 2, and then adding 19 to the result.
49+2x
40 + 2n
The expression that represents 5 less than twice x is ( 2x - 5 ). Here, "twice x" is represented by ( 2x ), and subtracting 5 from it gives us the final expression.
2X + 3
There are two possible (and different) answers: 2x + 3y = 12 or 2*(x + 3y)= 12 The first one is (twice a number) increased by (three times another) The second is twice (a number increased by (three times another)).

The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
