The expression "y - 3x + 4" is not a question, but rather a mathematical expression. It represents a combination of variables (y and x) and constants (3 and 4) connected by addition and subtraction operations. The final value of this expression will depend on the specific values assigned to the variables y and x. To simplify or evaluate this expression further, specific values for y and x would need to be provided.

(21-3)times(7+4)
4xy = 4(3)(-7) = - 84
5gz = 5 x 3 x 4 = 60
Unfortunately there is no expression to evaluate!

Okay, here is a postfix expression: 3 4 * 5 6 * + the evaluation: 3*4 + 5*6 12 + 30 42
2*3*4 = 24
To evaluate expressions by substitution, first identify the variable(s) in the expression and determine their corresponding values. Replace each variable in the expression with its given value. Finally, perform the necessary arithmetic operations to simplify the expression and obtain the final result. For example, if the expression is (2x + 3) and (x = 4), substitute to get (2(4) + 3), which simplifies to (8 + 3 = 11).
2(1,0) - 3(2,-1) = (-4,3)
12 - 10 + 4 = 6
To evaluate the variable expression 3a + 2b, you need specific values for the variables a and b. Once you have those values, you substitute them into the expression and perform the arithmetic operations. For example, if a = 4 and b = 5, then 3(4) + 2(5) = 12 + 10 = 22. This gives you the final value of the expression.
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
Evaluate the following expression to 4*(12.25-4)/(9+2)
